Five Executives in Defense Mission GovCon

The global defense industry, together with the aerospace sector, is seen to remain robust in 2021, according to the latest Deloitte report. 

In particular, defense budgets and revenues for government contractors in 2021 are projected to be relatively stable, as military programs continue to play a crucial role in national defense, particularly during geopolitical pressures. 

In addition, global defense spending is estimated to increase by 2.8 percent in 2021, breaching the $2T level. Various nations are expected to continue to spend on building their militaries as international relations remain unstable and the global pandemic persists. 

Analysts also predict that defense companies would engage in mergers and acquisition activities to build scale and capture greater value for long-term growth. 

The Potomac Officers Club – a division of Executive Mosaic – features five executives leading the defense mission and business areas of some prominent government contracting companies.

The company received the task order under the Department of Defense Information Analysis Center’s multiple-award contract vehicle, awarded by the Air Force’s 774th Enterprise Sourcing Squadron. 

The deal indicates that the organization will execute a technology program to enhance the mission systems in manned Navy Maritime Patrol and Reconnaissance Aircraft for Naval Surface Warfare Center Crane Division in support of the Naval Air Systems Command PMA 290. 

Twomey said the company will provide advanced digital engineering capabilities to the service.

The IT service organization is tasked to deploy technology services in P-3C Orion and P-8A Poseidon aircraft, applied to intelligence, surveillance and reconnaissance functions and to anti-submarine and anti-surface electronic warfare.

Before joining ManTech in September 2018, Twomey was the chief operating officer for almost two years at Phycal, spearheading the operations of the start-up company to design commercial processes for the production of bio-fuel and renewable chemicals.

He also served as executive vice president and later as president at L-3 Communications, Global Security and Engineering Solutions from 2009 to 2012.

According to Todorov, the company’s FAAD C2 system has been deployed in missions across forward operating bases and other international sites since 2005. 

Specifically, the FAAD C2 has been used in C-UAS and counter-rocket, artillery and mortar missions owing to its performance and easy integration with existing sensors, effectors and warning systems that open opportunities for real-time defense against short-range and maneuvering threats, Northrop Grumman said.
