BAE Systems, QinetiQ tasked with A2 Bradley hybrid electric drive retrofit

by Ashley Roque

The US Army has awarded BAE Systems with a USD32.3 million contract to refit two A2 Bradley infantry fighting vehicles with hybrid electric drives (HEDs) in a bid to produce additional power for future weapons.

In mid-July, the service announced the terms of the prototyping contract and said it is expecting to receive the retrofitted vehicles in two years.

“By rapidly prototyping HEDs on a small scale, we can jump-start advanced electrification and hybridisation of army platforms, and encourage our industry partners to invest in these products to meet army standards,” said Lieutenant General Neil Thurgood, the director of hypersonics, directed energy, space and rapid acquisition, who is also overseeing the Rapid Capabilities and Critical Technologies Office (RCCTO).

The service is eyeing the HEDs as a way to reduce fuel consumption, and increase reliability and performance without adding additional size, weight, and power (SWaP) demands.

This HED effort will consist of an upgraded engine, a transmission replaced by an electric drive motor, and the addition of lithium ion batteries. As a result, the engine power can produce electricity for greater mobility and can also be used to operate additional onboard equipment. One potential power use could include directed energy weapons, such as high-powered lasers, that pose numerous SWaP challenges.

“HEDs add a high-voltage generator that turns engine power into electricity for greater mobility and for operating additional equipment, both of which increase combat effectiveness,” Mike Foster, director of the RCCTO's rapid acquisition, said in the announcement.

    Army Takes Its Radio Network Commercial

    By SYDNEY J. FREEDBERG JR. ARLINGTON: As the Army reboots its battlefield radio networks, it's jettisoning exquisitely custom-made military waveforms and moving to simpler — but more capable — commercial radio protocols. The move is underway on three fronts, Maj. Gen. David Bassett, the two-star Program Executive Officer for command, control & communications – Tactical (PEO C3T), says: The Army's already moving its backpack-mounted tactical radio, the Manpack, from the milspec Soldier Radio Waveform (SRW) to the commercial TSM waveform, with both Harris and Rockwell Collins now integrating TSM in their radios. (Special operators already use TSM). They're currently selecting vendors to do the same for their handheld Leader Radio, mainly used by junior and non-commissioned officers on foot. Bassett's staff told me to expect an award sometime in September. They're exploring alternatives to the Wideband Networking Waveform (WNW) as the “backbone” of the Army's tactical network. TSM is one candidate but there are others, including some still in development, Bassett told me in an interview here. It's all part of a wider effort to rebuild the Army's command, control, and communications (C3) networks for war against a high-tech great power. Speaking at a cyber and networks conference held here Aug. 2 by the Association of the US Army, Bassett said the Army will conduct operational testing of new command systems — including two lower-complexity alternatives to complement the current mainstay, JBC-P — and start fielding them, he said, “this fall.” Why the rush? Army systems like WIN-T(Warfighter Information Network – Tactical) worked adequately as long as we had big bases in Afghanistan and Iraq, with plenty of time to set up extensive infrastructure and minimal enemy interference. China and Russia, however, have cutting-edge cyber and electronic warfare attackers to hack the network software, powerful electronic warfare units to jam its transmissions, and long-range precision guided missiles that can easily target large, stationary command posts. So last year Army Chief of Staff Mark Milley ordered a crash program of improvements, cancelling planned WIN-T upgrades in favor of new technologies, many from the thriving commercial IT sector. “It was kind of a shock to the system,” the Army's Chief Information Officer, Lt. Gen. Bruce Crawford, told the AUSA conference. “The Army came forward and said there were some programs it wanted to halt and some things it fundamentally wanted to do differently.” Appealing To Industry Gen. Milley's announcement met with initial resistance, including on Capitol Hill, but inspired intense interest from industry. Maj. Gen. Bassett himself had come to the AUSA conference from a meeting in Raleigh, one corner of North Carolina's thriving“research triangle,” where he had briefed 400 representatives from some 126 companies. “Down in Raleigh, the challenge that I gave them was learn how you fit into our network design. Propose solutions that will fit into our network,” Bassett said. “We want them to become part of that infrastructure rather than competing with it.” https://breakingdefense.com/2018/08/army-takes-its-radio-network-commercial-can-you-hear-me-now
