Northrop Grumman boosts B-2 digital communications

In an innovative stride, Northrop Grumman Corporation, together with the U.S. Air Force, has successfully carried out an integrated airborne mission transfer (IAMT) demonstration using the B-2 Spirit. This demonstration took place at the Whiteman Air Force Base and is a component of the latest series of modernization strategies which emphasizes the incorporation of digital engineering.

The primary focus of IAMT is to instill the B-2 with a sophisticated feature, allowing the aircraft to undergo a digital, machine-to-machine handover of novel missions that are received while in flight. This direct transfer ensures the missions are swiftly integrated into the aircraft system. Such advancements stem from Northrop Grumman's B-2 Collaborative Combat Communication (B2C3) Spiral 1 program. The initiative behind this program is to digitally augment the B-2's communication proficiencies in the contemporary battlefield scenario.

Nikki Kodama, Vice President and B-2 Program Manager at Northrop Grumman, elucidated the intent and implication of these enhancements. Kodama stated, "We are providing the B-2 with the capabilities to communicate and operate in advanced battle management systems and the joint all-domain command and control environment, keeping B-2 ahead of evolving threats." Kodama also accentuated the importance of this integration, mentioning that merging this digital software with their weapon systems would "further enhance the connectivity and survivability in highly contested environments" as an integral facet of their modernization pursuits.

The demonstration witnessed a rigorous testing phase spanning two days. Throughout this period, about 50 mission transfers were accomplished in collaboration with the Air Force. The aircraft under the spotlight was vehicle 1086, known as the Spirit of Kitty Hawk. This aircraft was equipped with Northrop Grumman's cutting-edge Multi Mission Domain (MMD) architecture. The MMD can be described as an open mission system specifically devised for the B-2, paving the way for the swift and economical deployment of updated mission capacities. A notable feature of this demonstration was how the MMD played a crucial role in integrating with the B-2 Adaptable Communications Suite (ACS).

When delving into the specifics of the demonstration, it was observed that the aircrew obtained an inbound transmission stemming from the ACS ground station. This transmission was subsequently loaded directly to the B-2 Disk Drive Unit via the MMD interfaces. The key takeaway is that with the advent of such progressive digital technology, the B-2 flight crews will be able to channel their attention and efforts more towards the execution of the mission, particularly in the fluctuating landscapes of today's battlespace.

Military-run Mexican airline to take off in December
Mexico City (AFP) Aug 10, 2023
Mexico will launch a new military-run, low-cost airline in December after buying the brand of a carrier that went bankrupt 13 years ago, President Andres Manuel Lopez Obrador announced Thursday. The government said that it was paying nearly $50 million to be shared among around 7,400 former employees of Mexicana de Aviacion, which collapsed in 2010. An additional $235 million will be invested in the business, which will have a fleet of 10 leased Boeing 737-800 aircraft, it said. The airline, ... read more
