The AN/AAQ-37 Distributed Aperture System (DAS) is the first of a new generation of sensor systems being fielded on the Lockheed Martin F-35 Lightning II. DAS consists of six high-resolution infrared sensors mounted around the F-35's airframe in such a way as to provide unobstructed spherical (4π steradian ) coverage and functions around the ...
According to the manufacturer's specifications, the systems weigh from 15 to 320 pounds (7 to 145 kg) and can emit sound in a 30°- 60° beam at 2.5 kHz. [62] They range in size from small, portable handheld units which can be strapped to a person's chest, to larger models which require a mount. [63]

The Pratt & Whitney XA101 is an American adaptive cycle engine demonstrator being developed by Pratt & Whitney for the Lockheed Martin F-35 Lightning II and form the technological foundation for the company's XA103 propulsion system for the United States Air Force's sixth generation fighter program, the Next Generation Air Dominance (NGAD).
PITA is a full complement of the engine power head system but without turbo pumps. [33] It was proved that the pre-burner could ignite smoothly and continuously. A start fuel ampule that combines triethylaluminium and triethyleboron created by Vikram Sarabhai Space Centre (VSSC) is used to ignite semi-cryogenic engine and utilized for the first ...
This engine also powered (or was an option to power) the "D" and "E" variants of the MQM-107 target drone. [7] The "5+" variant powers the BQM-167 Skeeter target drone. The 5+ model also demonstrated the engine's supersonic flight capability in 2007. As of 2008, this is the last three-compressor-stage variant of the TRI 60 in production. [1]
Precision-guided small arms prototypes have been developed which use a laser designator to guide an electronically actuated bullet to a target. [83] Another system in development uses a laser range finder to trigger an explosive small arms shell in proximity to a target. The U.S. Army plans to use such devices in the future. [84]
A major redesign of the Gripen series, previously referred to as Gripen NG (Next Generation) or Super JAS, now designated JAS 39E/F Gripen [6] began deliveries to the Swedish Air Force and Brazilian Air Force in 2019. Changes from the JAS C to JAS E include a larger fuselage, a more powerful engine, increased weapons payload capability, and new ...
