## What project 675345 buys

The B-2 is currently undergoing modernization of avionics, communications systems, cockpit displays, armament systems, low observable components, core training system components, aircraft supportability improvements, and support equipment development. The Air Force will continue to study multiple structural, avionics, and engine modifications, as well as advanced weapons integration, communications upgrades, and innovative low observable enhancements, that could improve the performance of the aircraft and engines and reduce maintenance man-hours and the logistics footprint of the fleet. The Adaptable Communications Suite (ACS) Increment 4.0 provides secure beyond line-of-sight Satellite Communication (SATCOM) Command and Control connectivity. ACS 4.0 will replace the current radios and ancillaries to transition the B-2 SATCOM's capability from the Ultra High Frequency Follow-On (UFO) satellite constellation, which is reaching end of life, to the Mobile User Objective System (MUOS) satellite constellation bringing enhanced security and functionality for beyond line-of-sight (BLOS) communications. Along with the aircraft system, the ACS ground systems and infrastructure will be redesigned to support this new waveform. ACS 4.0 significantly improves the transfer time for real-time mission planning data and allows for simultaneous use of SATCOM voice and data. Answering the warfighters requests for additional highly secure communications pathway, funds will support the development and integration of Digital High Frequency (HF) radio suite and Alternative Communications radio, that will enable the B-2 to communicate and receive critical messages while operating in highly contested environments. This capability can be used globally, but it is critical once the B-2 enters a highly contested airspace. B-2 Battlespace Collaborative Combat Communications (B2C3) effort integrates an independent Open Mission Systems (OMS) avionics architecture on the B-2, as well as upgrades the B-2's current line-of-sight (LOS) capability. B2C3's objective is to identify, leverage, and integrate existing capabilities to meet Air Force Global Strike Command's B-2 communications requirements. B2C3 will be implemented in two main increments defined as Spiral 1 and Spiral 2.

**R-3 lines of work:** Product Development; Support; Management Services.
