On 2019, the U.S. Department of Defense issued a memo, signed by the Secretaries of the Army, Air Force, and Navy, mandating the use of the Modular Open Systems Approach (MOSA). The memo stated that MOSA supporting standards should be included in all requirements, programming and development activities for future weapon system modifications and new start development programs to the maximum extent possible. In fact, this mandate for MOSA is even codified into a United States law that states all major defense acquisition programs (MDAP) are to be designed and developed using a MOSA open architecture.
MOSA itself is not a technical standard, but an acquisition and design strategy that prioritizes the use of open standards-based technology. The MOSA directive has accelerated the adoption of a variety of open standards, such as SOSA or CMOSS, that have been adopted by the three military branches.
Adopting a MOSA open architecture allows:
Seamless Sharing across Domains and Machine
Rapid Innovation and Integration
Vendor Independence and Reduced Obsolescence
Life Cycle Supportability

Security in military systems helps combatants to carry out their missions reliably. That is why all the hardwares and softwares that are used must be designed to its safe use.
Once they are started, special attention is required to ensure the operation goes as planned. This is usually complicated, since very few developers have access to the application code, not to mention that, as usual, these applications are custom designed to execute a specific mission, so the review which is usually done is always at a general level.
This lack of in-depth review of the particularities of each software can result in undiscovered vulnerability. In addition, it must be borne in mind that application codes of military systems are usually tested at the beginning and, once implemented, they are no longer subject to further tests. All this makes discovering security flaws over time very complicated.
If we continue with security problems, we must add that, normally, there are budget and time constraints, leaving the software updates aside, especially if it is already being used in missions. Moreover, even if security failures are discovered, the costs of correcting that failure are usually excessive, so they are not fixed.
To avoid all of this once the softwares are implemented, it is important to use all kinds of techniques to detect failures before the implementation is carried out. In addition to delivering safer products, you save time and money in the long run. For this reason, it is imperative that system developers make the right decisions about the application code from the beginning.

Integration of systems and fulfillment of requirements for management programs are a headache for the aerospace sector companies. That is why Curtiss Wright has been working on these issues for decades.
Thanks to their work, it is possible to maximize the COTS content, as well as taking advantage of one of the existing customized solutions in order to take full advantage of the systems integration.
In order to guarantee success, you can create your own application using the Curtiss Wright generic systems or, alternatively, use your experience in the sector and design a specific systems solution with optimized functionality adapted to a specific program or platform.
These products include rugged systems for the mission, such as Parvus DuraCOR, which have modular and expandable designs with great data and graphics processing capabilities that, along with their mechanical robustness, make them highly reliable products.
Thanks to the use of pre-integrated subsystems and pre-qualified, customers greatly reduce the programming risk, as well as the general expenses of program management, also maximizing the use of COTS technology in open architecture.

SFF is one of the terms which is becoming increasingly important in the aeronautical market.
SFF stands for Small Form Factor, an upward trend. As you know, technological advances allow us to improve the success of surveillance missions as new and better capabilities are added to carry out these missions. The problem with this is its new technology takes up space and adds weight, something that goes against the limited space inside vehicles and aircrafts. In addition, adding weight negatively affects fuel and power, so this is not a viable solution.
To deal with this problems, there is the Small Form Factor, an alternative capable of optimizing electronic systems. Leaving aside the equipment with cutting-edge technology, or reducing its scope, should not be an option if you want to achieve good results. Therefore, Curtiss Wright is committed to the distribution of flexible and interoperable video management in which size and weight reduction, without affecting power, is the key.

ARM stands for Advanced RISC Machine and refers to processors that are capable of providing the most advanced smartphones and mobile devices with great performance.
The relentless advance of commercial mobile devices has driven the designers to create smaller, faster processors that consume less and less energy and offer, at the same time, safe and complete computing. This combination can also be featured in defense applications, as well as in aerospace applications with incredibly high demands.
These applications’ processors must perform as expected from this type of item; in addition, they have to provide a fundamental factor based on the severe restrictions in size, weight and power (SWaP) and cost, given the budgetary pressure within the market.
In conclusion, ARM technology makes it possible for chip suppliers to develop 32-bit and 64-bit processors that work well beyond the required level, providing good performance with low power, low space and low cost, without compromising the information’ security.
