Manufacturing with Shelter Service Companies

What are Shelter Companies?

third part supplier through shelter service company

A shelter company is a third-party supplier that provides real estate and other resources to complete a project. At the same time, the hiring party retains full control.

Through a Mexican government-supported shelter program, companies do not have to pay income tax in Mexico for four years, while the Mexican shelter company “shelters” the foreign company with a manufacturing facility, raw materials, and more.


When a Mexican company is there to offer shelter services, they will secure licenses and permits needed to operate in place, allowing production to commence much faster.

Most companies that operate under a shelter contract manufacturing can be up and running in Mexico in just 3-6 months.

What Shelter Services are offered?

Besides obtaining licensing and permits, manufacturing communities offer various service needs. Shelter companies in Mexico provide administrative services such as HR and accounting, advisors to deal with Mexican legalities, and all the core manufacturing functions needed to carry out the manufacturing operation.

Risk & Liability

When working with a shelter company, the provider assumes much legal risk and liability. It is up to the shelter company to ensure all compliance measures are being met and that rules and regulations are being carried out appropriately.

Services offered by Shelter Companies in Mexico include:

  • Human resources and recruiting
  • Employee payroll and benefits administration
  • Customs management and import/export administration
  • Tax and fiscal compliance issues
  • Environmental and occupational health and safety
  • Purchasing negotiations and vendor relationships
  • Facilities management and real estate

The benefits of working with a Shelter Company

Access to a skilled workforce

Skilled labor, is defined as at least five years in an industry-specific role, is plentiful in Mexico. In recent years, Mexico has made it a priority to provide exceptional service to manufacturing companies. As a result, the Mexican workforce is filled with highly skilled workers who bring value to operations.

Room to grow

human resource management

A growing business means a growing output of products, but it also requires growth behind the scenes to hire more employees, organize larger-scale accounting, and more. When working with Mexico shelter companies, all of these areas are accounted for. The right shelter service provider is there to help keep up with the growth of your business.

Lower Costs

The Mexican government views the shelter manufacturing model very favorably, benefiting the Mexican economy. Companies operating under the shelter service model are rewarded through income, consumption, and import/export tax incentives.

Doing Business with Foreign Companies

mexica shelter service company

In recent years, China has been the hub for manufacturing outside the United States. Still, many businesses have been looking for an alternative closer to home with various growing issues, including cost and supply chain.

Manufacturing with Mexico shelter services offers foreign companies tax advantages, cost savings, and a skilled industrial workforce to support their manufacturing operations. There are several options available when setting up a new operation in Mexico. However, working with a shelter program is one of the most cost-effective, efficient, and safest ways to save on everything from janitorial and security costs to logistics and customs fees while completing a project.

Platter Slip Rings

Platter Slip Rings

What is a Slip Ring?

A slip ring is an electromechanical device that allows the transmission of power and electrical signals from a stationary to a rotating structure.

A slip ring is a method of making electrical contact to form rotating assembly. It is an electric transmission device that allows energy flow between two electrical rotating parts, such as in a motor.

When are Slip Rings the Right Solution?

A slip ring is the ideal solution for any electromechanical system that requires rotation while transmitting power or signals. Slip rings are used in virtually any application that includes a rotating base or platform. They can improve mechanical performance, simplify system operation and eliminate damage-prone wires dangling from movable joints.

Slip Rings in Motors

Slip rings can also be used to created desired resistance. In the case of AC (alternating current) motors, for example, slip rings do not transfer power but create tension. By creating resistance in rotor wirings, mounted to but insulated from the rotor shaft.

Adding the desired resistance to rotor windings helps to match the rotor current with the stator current. The result is higher torque, even with a relatively low current.

Minimum Amount of Current Needed

Platter Slip Rings used in cpu

The design and bore size of a slip ring will depend on its application. A more advanced design might be required to complete the request of transmitting data, for example.

The case of data transmission requires a slip ring with higher bandwidth and better EMI contact mitigation than one that transmits power services exclusively.

 Regardless of intended use, the basic details are mounted in much the same way. Once the customer has made the intended use clear, the proper slip ring application will become apparent.

Types of Slip Rings

Pancake Slip Ring

In a pancake slip ring, conductors are arranged on a pancake-like disk. Pancake slip rings are specially designed for applications with limited space.

Mercury Contact Slip Ring

Mercury contact is used for conducting. This allows the transfer of currents and electrical signals via the liquid metal.

Durability, stability, and quiet operation make mercury contact slip rings and efficient choice.

Wireless Slip Ring

A wireless slip rings allows for the transfer data and power wirelessly using an electromagnetic field.

The wireless slip ring reduces mechanical contacts and maintenance, making it well suited to harsher environments and use.

Through Hole Slip Ring

A slip ring with a hole in the center. This kind of slip ring is used in rotating devices that need to transmit a signal.

A through hole slip ring includes the benefits of longevity and quiet operation.

What is Plating?

metal plating machine

Plating is a manufacturing process in which a thin layer of metal coats an underlying substance. This can be achieved through electroplating, which requires an electric current, or through electroless plating, which is in autocatalytic chemical process.

Metal plating has been used for hundreds of years and is a critical part of corrosion resistance. The reasons for metal plating include:

  • Corrosion resistance.
  • Improved paint adhesion
  • To harden the surface
  • Improves the look of cheaper metals in jewelry
  • Reduce friction
  • Improve the wearability of the part
  • Alter conductivity (more or less conductive)
  • Acts as a shield against radiation

Nickel Plating

nickel plating

Nickel plating provides a unique combination of corrosion and wears resistance. It can add brightness, luster, and appeal. It also provides excellent adhesion properties for subsequent coating layers as nickel plates commonly bond well with other materials, which is why nickel is often used as an ‘undercoat’ for other coatings, such as chromium.

Nickel Plating is widely used, pointing to its beneficial properties and versatility as a coating material.

Gold Plating

Often seen in jewelry, gold plating refers to a method of coating the surface of a metal (which is mostly silver or copper) with a thin layer of gold. Some other metals gilded with gold are stainless steel, nickel, brass, titanium, and tungsten.

Not all gold plating is created equal. Which base metal is used, the application skill, and the thickness of the coating all determine different looks and quality.

Silver Plating

Silver electroplating is one of the oldest plating processes. Silver plating uses date back to the beginning of coinage and metal smithing. Silver is the least expensive precious metal, is actually harder than gold, and is very conductive.

Known for its hardness and corrosion resistance, silver plating exhibits excellent anti-galling properties, high lubricity, a wide operating temperature range, good corrosion resistance, and exceptional conductivity.

Copper Plating

copper wire

The copper plating processes are one of the best for electrical conductors. As copper is a soft metal, it can be applied to metal parts that require some flexibility, which is why it is often found in wiring.

In the process of copper plating, copper sulfate acts as an electrolyte, copper wire dipped in electrolyte works as an anode and an iron rod to be plated is dipped in electrolyte and connected externally as a cathode.

When gold plating copper, the copper is usually plated with nickel before being plated with gold, as the copper may otherwise migrate into the gold over time.

What is Cadmium Plating?

Cadmium plating is a metallic silver, soft coating that can be deposited on various base materials such as steel, copper, iron, brass, and aluminum. It is prized for its corrosion resistance, lubricity, chemical resistance, ductility, and ease of solderability.

Other plating metal processes include zinc plating, chrome plating, and tin plating, all of which are commonly used to improve oxidation and electrical conductivity.

Kinds of Plating Processes

1.) Electroplating

Electroplating is the most common method of plating. Electroplating uses an electrical current to dissolve positively charged metal particles (ions) in a chemical solution. The positively charged metal ions are attracted to the material to be plated, which is the negatively charged side of the circuit. The part or product to be plated is then placed in this solution, and the dissolved metal particles are drawn to the material’s surface. Electroplating results in a smooth, even, and rapid coating for the material that is plated, effectively changing the material’s surface. There are a number of different steps and processes that can be involved in electroplating, including cleaning, striking, electrochemical deposition, pulse electroplating, and brush electroplating.

Electroplating forms a protective barrier against atmospheric conditions such as corrosion. It can also enhance the heat resistance and make the piece stronger against impacts and shocks if the underlying metal is brittle.

Electroplating helps to reduce friction by allowing components to slide more easily across adjacent surfaces, without heating or scraping. Proper plating increases efficiency and decreases premature wear and tear.  

Electroplating is becoming an extremely common preference in manufacturing processes where extreme thickness is required. The thicker the coating is the more durable and wear and tear resistant it is, meaning it can last longer. It enhances the overall consistency and improves the substrate’s durability.

2.) Electroless (Autocatalytic) Plating

Electroless plating is so called because it is a plating method that does not use external electric power. This common electroless plating method involves a chemical reaction that induces metal atom reduction. In other words, the solution of metal ions (particles) when mixed with a reducing agent is converted into a metal solid when they come in contact with the catalyzing metal (which triggers the reaction). This results in the metal being plated with a solid layer of the plating metal.

Advantages of electroless plating include:

Advantages of Electroless Nickel Plating

  • Excellent wear and abrasion resistance
  • Good ductility, lubricity and electrical properties
  • High hardness, especially when heat-treated
  • Good solderability
  • Even and uniform thickness even down deep bores and recesses, and at corners and edges
  • The coating can be applied as the final production operation and can meet stringent dimensional tolerances
  • Can be used on both metallic and non-metallic substrates, provided they have been suitably pre-treated

3.) Immersion Plating

Immersion plating involves immersing one metal into a solution of metal ions from a more noble metal. The ions from the nobler metal are more stable, and so there is a natural ‘pull’ to displace the surface metal ions from the less noble metal with a thin layer of the nobler metal ions. Immersion plating is a slower process, and can only be used for plating less noble metals with nobler metals. Nobler metals are chemically inert metals. For example gold, platinum, or silver.

Immersion plating is distinct from various electroplating processes in the sense that there is no presence of external current. Unlike with electro-less plating, the deposition of metals is halted once the plated object is completely coated with metals of higher nobility. This type of plating occurs at high temperatures.

Immersion plating benefits include:

  • Wear and corrosion resistance
  • Electrical resistance
  • Electrical conductivity
  • Appearance and reflectivity
  • Chemical resistance and hardness
  • Torque tolerance
  • Bonding capabilities

Computerized Manufacturing

Computerized manufacturing refers to the dynamic future of computer aided design and manufacturing. Often referred to as CNC, computerized manufacturing and machining plays a vital role in the evolving world of modern manufacturing. But what is CNC, exactly? How does it play a role in the manufacturing industry, and what do CNC machinists do? How can you find the right CNC machinists who have taken the time to gain job ready skills fit for the world of CNC machining today?

What is Computer Integrated Manufacturing?

CNC or Computer Numerical Control machines are automated machines operated by computers executing a pre-written program. Today’s modern CNC machines help to replace the need for workers dealing directly with dangerous equipment by manufacturing a system that understands computer code, which can be written to produce precise measurements for production, like feed rate, speed, location, and coordination.

Computer Aided Drafting Techniques

Computer-aided design and drafting systems have increased design and drafting productivity. This aspect of computerized manufacturing takes work that is traditionally done by manual drawings using pencil or ink and upgrades it to a sophisticated software.

Computer Aided Process Planning

Computer-aided process planning, or CAPP, involves using computer technology for designing physical products. It goes along with things like computer-aided design (CAD) and computer-aided manufacturing such as CNC mentioned above, but computer-aided process planning focuses on industrial processes.

Finding the Right Operators

In order to be competent and gain knowledge about CNC technologies, machinists must first be students willing to complete two years of quality education in the field. CNC machinists require additional information and skills compared to manual machine operators, and a proficiency should be established before hiring.

Printed Circuit Board Tape

What is a Printed Circuit Board?

printed circuit board

Printed circuit boards, abbreviated as PCBs, are the foundational building block for most electronics manufacturing.  A high-density, high-speed circuit board may be used in supercomputers and servers. Printed circuit boards are the foundation on which all other electronic products are assembled.

PCBs have mechanical and electrical components that make them ideal for electronic applications.  Most PCBs manufactured are rigid, but some PCBs are flexible, allowing the circuits to be bent and folded into shape without any break in the circuits.  These flexible PCBs comprise roughly 10% of the market. 

A small subset of these types of circuits is called rigid-flex circuits, where one part of the board is rigid and one or more parts are flexible, providing the advantages of flexible circuits listed above.

What are PCBs made of?

printed circuit board

Typically, PCBs are made from non-substrate materials with layers of copper circuitry. PCBs can be single-sided (one copper layer), double-sided (two copper layers on both sides of one substrate layer), or multi-layer (outer and inner layers of copper, alternating with layers of the substrate). A multi-layer PCB allows for much higher component density because circuit traces on the inner layers would otherwise take up surface space between components.

PCBs are also typically comprised of bonding and protective elements, such as rubber adhesive, polyimide film, polyester film, or blended silicone to help the board withstand high temperature and a variety of other stressors.

The rise in popularity of multilayer PCBs with more than two, and especially with more than four, copper planes was concurrent with the adoption of surface mount technology. However, having a multilayer printed circuit board makes the repair, analysis, and field modification of circuits much more difficult and often impractical.

Wave Soldering Process

Wave soldering is a bulk soldering process used for the manufacturing of printed circuit boards. The circuit board is passed over a pan of high temperature, molten solder in which a pump produces an upwelling of solder that looks like a standing wave. As the circuit board makes contact with this wave, the components become soldered to the board.

Wave soldering is used for both through-hole printed circuit assemblies and surface mounts. In the latter case, the components are glued onto the surface of a printed circuit board by placement equipment, before being run through high-temperature applications like the molten solder wave. Wave soldering is mainly used in the soldering of through-hole components.

As through-hole components have been largely replaced by surface mount components, wave soldering has been supplanted by reflow soldering methods in many large-scale electronics applications. However, there is still significant wave soldering where surface-mount technology is unavailable or not suitable, such as with the assembly of large power devices.

Why Mask a Printed Circuit Board?

Printed circuit boards have connectors, test sites, and pins where electrical continuity needs to be maintained, which means conformal coating can not be applied to those specific points.  There are also other points of a board that needs to be masked, such as unsealed components (like relays or open inductors), through holes, and even LED surfaces where light output may be impacted by the coating.

Masking tape for a Printed Circuit Board

printed circuit board lab

Low-ESD Polyimide Tape

The ideal tape for masking printed circuit boards is the low ESD (Electrostatic Discharge) polyimide tape. The low ESD function reduces the discharge of electroplating static upon the tape’s removal. Low ESD polyimide also adheres strongly without leaving behind residue on the gold fingers or other components of the circuit board.

Crepe Masking Tape

Another great option for printed circuit board tape is crepe masking tape. It has the lowest price and less risk of static damage compared to polyester tapes. The drawback to this option is that it’s not as flexible as polyimide, so won’t conform as well. An additional benefit of crepe tape is that it uses a rubber-based adhesive instead of silicone, helping reduce the rise of silicone residue remaining on the board.

Polyimide Tapes

Another very popular and effective choice for masking printed circuit boards is standard polyimide tape. Polyimide tape is flexible, doesn’t leave behind any residue, has very high-heat resistance, and comes in a variety of different sizes.

Nearshore Manufacturing

What is Nearshore vs Offshore Manufacturing?

You may be familiar with “offshore” manufacturing as a way to reduce production costs, but, for many manufacturers, that has started to change. More manufacturing operations are now considering “nearshore” manufacturing as a way to balance both labor and operational cost savings. 

What is Nearshoring?

nearshore manufacturing

So, what is nearshoring? Nearshore manufacturing is defined as moving production of a good to a nearby country where labor costs may be lower. That other country may share a border or time zone with the home office as opposed to far off foreign companies, boosting collaboration, reducing freight costs, and at times leading to lower labor costs.  

Unlike outsourcing, nearshoring implies that the new manufacturing site is a strategic partner, rather than a subcontracted team working to a level of quality it decides is adequate. 

Benefits of Nearshore Manufacturing Operations

Supply Chain Stability

supply chain stability

Working with foreign manufacturers in asian countries or on the other side of the world could mean a 12-hour delay in response time and production changes. This level of improved time management that can drive greater project efficiency for your manufacturing business.

Nearshore manufacturing bolsters a company’s ability to regularly visit new operations, audit new processes, or send experienced managers in to train supervisors.

The cost of sending managers from the U.S. to Mexico, for example, is much more affordable than flying to Asia or India.

Cultural Differences

Operating in a foreign country may require employers to gain an understanding of local expectations and cultural norms.

Differences in culture tend to be less of an issue when operating closer in proximity to the home office, where customs may be more familiar. This edge matters, as communication challenges can lead to production problems, slower acquisition of raw materials, and differences in free trade agreements.

Labor Costs

Wages and currencies have been fluctuating massively for offshore manufacturing in China and other relatively low-labor-cost countries.

labor costs

For many products, the base price of those sourced in low-labor-cost countries will almost always be lower than the price for the same product manufactured in higher-labor-cost locations.

However, when companies focus only on price and labor, they downgrade all other priorities. When considering the total cost-benefit analysis (saving on transportation, shipping, smoother production, and more), moving manufacturing closer to the end customer usually proves to be the wiser, most cost-effective choice.

Growth of Manufacturing through Greater Proximity

With the convenient proximity of working in a neighboring country, small and medium manufacturers can gain the edge they need to open to new markets and grow financially while staying close to their clients.

The potential for overall operational cost savings increases when working with a strategic partner that can help with a site selection and talent recruitment plan, armed with local insight and cultural understanding, to maximize your chances of success. 

Why Choose Manufacturing in Mexico?

mexico manufacturing

Not only does Mexico meet the benefits listed above, it also offers a high level of quality in the manufacture of complex products. 

Manufacturing in Mexico meets the excellence needed for complex production ranging from aerospace components to medical devices and automobiles.

That skill comes in part through investment from federal and state governments and corporate partners in specialized training programs dedicated to manufacturing job growth.  


After several years of discussion and negotiation, the U.S.-Mexico-Canada Agreement (USMCA) officially replaced the North American Free Trade Agreement (NAFTA) on July 1, 2020. The new free trade agreement brings changes for companies already operating in Mexico as well as those considering manufacturing in Mexico for its nearshoring benefits. 

USMCA brings dramatic adjustments to supply chains and broadens requirements for documentation. USMCA carries great potential for strengthening trade between Mexico, the United States, and Canada.

While the new agreement does not benefit countries in Central America, such as Costa Rica, moving Manufacturing to Mexico for those in Mexico’s proximity allows for greater advantages under the new USMCA agreement.

Fiber Optic Polishing

The fiber optic polishing process removes any excess epoxy or fiber stub left after cleaving, shapes the ferrule, and removes scratches in the glass, enabling an end finish that passes optical signals with minimum loss. It affects two types of optical loss: insertion loss and return loss.

Insertion Loss

fiber optic cable

Insertion loss is the amount of energy that a signal loses as it travels along with a cable link. It is a natural phenomenon that occurs for any type of transmission, whether it’s electricity or data.

Pre-polished connectors offer a quick and reliable alternative to unpolished connectors for horizontal and backbone termination applications. With good installation practices and attention to detail, installers can expect high termination yields and low insertion loss values.

Return Loss

Return loss is a measure of reflected light. Whenever light encounters a change in the refractive index of the material through which it is propagating, a portion of the light is reflected back toward the optical fibers.

Some of this reflected light can interfere with the proper operation of light sources, especially lasers. Because of its small core size, a single-mode fiber connection requires a high return loss to limit the amount of reflected energy.

Polishing surface area removes any excess epoxy or fiber stub from the fiber connector left after cleaving, shapes the ferrule, and removes scratches in the glass, enabling an end finish that passes optical signals with minimum return loss.

Fiber Optic Connectors

Most fiber optic connectors are plugs or so-called male connectors with a protruding ferrule that holds the fibers and aligns fibers for mating. They use a mating adapter to mate the two connector ferrules that fits the securing mechanism of the connectors (bayonet, screw-on, or snap-in.) The ferrule design is also useful as it can be used to connect directly to active devices like LEDs, VCSELs, and detectors.

Polishing Process

Fiber Optic Polishing

Polishing the fiber/ferrule end faces of a fiber-optic connector critically influences optical performance and is highly susceptible to error. Yet the polishing process is neither difficult nor mysterious. Other steps in the connector termination procedure, such as crimping, involve mechanically securing the fiber in the connector.

As the final step, polishing machines prepare the fiber optically to ensure that defects and nonuniformities in the fiber/ferrule end faces or geometry do not degrade the passage of light across the connector joint.

Singlemode Polishing

Singlemode fiber polishing is a multistage process that begins with a quick, coarse polish and ends with a final polish in a slurry. Different polishing materials are involved in each step. In most cases, a single mode fiber connector uses epoxy to hold the fiber within the ferrule. A six-step process ensures the proper techniques for polishing a single-mode fiber-optic connector.

Step one:

The first step consists of a quick hand polish with medium pressure applied using a coarse polishing film. This step removes the fiber stub and levels the protruding material (including a glass plate or epoxy) close to the ferrule.

Step two:

The second step requires a 5-micron aluminum-oxide film. Hand-applying the lapping film gently across the four corners of the fiber end face removes the epoxy down flush with a ceramic ferrule. However, this action could remove some ceramic material as well.

Step three:

In the third step, a medium-grit diamond film is used to begin shaping the fiber/ferrule end faces. Unlike aluminum oxide, the diamond film treats ceramic and glass materials similarly. This shaping minimizes undercut so that the fiber recedes only slightly into the ferrule. Because the main purpose of this step is shaping, it usually leaves visible scratches on the fiber end face.

Step four:
fiber optic cable

To remove scratches and achieve a smooth surface, a fine-grit diamond film is used next in step four. In terms of insertion loss, the finish should be acceptable at this point.

However, to obtain a high-return loss of at least -45 dB, we strongly recommend a fifth or finish step because of the altered-index layer on the fiber connectors.

During abrasive polishing, a small layer on the end of the fiber pads become altered so that its refractive index changes. This change increases reflections, producing a lower return loss, and the fifth step of the slurry polishing film is needed to remove the altered layer.

Step five:

The fifth step uses a special polishing film, which contains a top layer of the polishing slurry. Typically used while being suspended in distilled water, the slurry has both a lubricating and chemical effect on the fiber during hand application to change the refractive index back to its original value.

Step six:

The last step involves inspection. The use of a hand microscope determines polishing acceptance or nonacceptance.

Rubber Polishing Pad

Rubber pads play a critical role in polish results and are often overlooked.

Having a consistent hardness across the surface of the rubber pad is necessary for producing consistent polishing results. Rubber hardness will change over time, so rubber pads always need to be replaced periodically (annually, at minimum).

When your radius values are under control, another key geometry parameter is your Apex. This reflects the angle of the polished end-face.

If the Apex values are too large, this means your ferrules are being polished at an angle that is too large. All other conditions being equal, a smaller Radius value will generally result in a better Apex value.

If you’re already dialed in on desired Radius values and the Apex values remain unacceptable, the cause is likely related to worn polishing fixtures or worn rubber pads. In both cases, the only fix is to replace the worn fixture or rubber pad.

What is the Aerospace Industry?

Aerospace is a term used to collectively refer to the atmosphere and outer space. An aerospace-related activity is very diverse, with a multitude of commercial, industrial, and military applications. Aerospace engineering consists of aeronautics and astronautics.

Aerospace organizations research, design, manufacture, operate, or maintain aircraft, spacecraft, and related topics.

The beginning of space and the ending of the air is considered as 100 km (62 mi) above the ground according to the physical explanation that the air pressure is too low for a lifting body to generate meaningful lift force without exceeding orbital velocity.

Manufacturing for the global aerospace industry

The global aerospace parts manufacturing market size is expected to reach USD 1,233.2 billion by 2030. Increasing passenger and freight traffic in emerging economies and the addition of state and local incentives are driving the demand for next-generation aircraft, which in turn is expected to boost the market growth.

A majority of aerospace manufacturing companies are integrated across the value chain and are highly active in the parts manufacturing process. These aerospace companies have in-house production facilities as well as supplier contracts for the procurement of these parts.

Raw Material Procurement

Aerospace manufacturing is also involved in raw material procurement and designing and quality control of the parts offered by third-party suppliers.

Aerospace companies are becoming more global due to heightened competition, growing travel demands, and increased security requirements in emerging markets. Globalization provides opportunities for lower costs and for technologically advanced product introductions.

Increasingly, these products can be designed and manufactured virtually anywhere. Globalization is also affecting product selections, in that military and commercial customers alike are requiring that value be “offset” by placing work closer to their countries of origin.

United States Outlook

This tendency is likely to continue, as traditional countries are pressured to keep their jobs at home, but is balanced by the need for companies to grow revenues and continue to reduce labor costs. The trend in the industry towards globalization is also marked by new market entrants, particularly in the commercial aircraft segment.

Reducing defense expenditures

No matter the outcome of the budget sequester action, there is likely to be continued pressure to reduce defense expenditures. Continued debate on several important questions regarding united technologies US defense and security policy and investment priorities are expected to shape the financial performance of the defense industry.

The formulation of a renewed US defense strategy, coupled with the resulting warfighter requirements, and ultimately the defense budget, will likely provide the guidance necessary for defense contractors to size their workforce appropriately, to understand what revenues they can count on, and therefore what their financial performance will be.

Political leaders of China, the U.S., the Middle East, and Russia are increasingly spending billions of dollars in military expenditure. Overall, the U.S. holds the largest share of worldwide military outlays; the country accounts for around 40 percent of global defense spending. Conflicting interests between countries’ expansion services stress the development of more military technology innovations. For instance, drones have become an indispensable weapon and are in great demand in many parts of the world.
