Sept. 4 (UPI) -- Lockheed Martin, General Atomics and Boeing have received contract modifications for drone-mounted Low Power Laser Demonstrator system missile defense testing.
Lockheed Martin's contract has increased to a total value of $37.7 million, while General Atomics and Boeing's have been increased to $34 million and $29.4 million respectively, the Department of Defense announced on Friday.
Work for all three companies will take place in various locations across the United States. The contract modifications come from the Missile Defense Agency and can extend as far as July 2019.
Specifications listed include a flight altitude of at least 63,000 feet, the endurance to stay on station for at least 36 hours after a transit of 1,900 miles, and a cruising speed of up to Mach .46 while patrolling its station.
The aircraft needs to be able to carry a payload between 5,000 and 12,500 pounds and sufficient power generation to operate a 140 kilowatt laser, with the possibility of up to 280 kw or more.
The system must also be able to operate the laser for at least 30 minutes without affecting flight performance, and be capable of carrying a one- to two-meter optical system for the laser.
The Missile Defense Agency is responsible for the defense of U.S. territory and its allies from ballistic missile threats. It coordinates a network of land-based and ship-based missile interceptors, along with radars and satellites to detect and destroy enemy ballistic missiles.
ICBMs are at their most vulnerable during their boost phase. A UAV capable of targeting them before they exit the atmosphere would greatly increase the possibility of intercept, the Pentagon said.

La France mène cette semaine son premier exercice militaire spatial afin d'évaluer ses capacités à protéger ses satellites, dans un espace de plus en plus militarisé. « Notre but est de montrer que la stratégie spatiale de défense n'est pas qu'un document, mais qu'on passe de la parole aux actes », a expliqué, mardi 9 mars, lors d'une conférence de presse, le général Michel Friedling, en charge du Commandement de l'Espace. L'ensemble de l'exercice, qui a lieu au CNES à Toulouse, reste virtuel : aucune véritable modification de la trajectoire des satellites français ne sera opérée. 60 militaires du commandement de l'espace y participent. La « Space Force » américaine et le Centre de situation spatiale allemand ont été invités à s'y joindre. Le CNES, l'ONERA, Safran, ArianeGroup et CS Group sont aussi mobilisés. La stratégie spatiale de défense a prévu un investissement de 3,6 milliards pour le renouvellement des capacités satellitaires de l'armée française, avec les nouveaux satellites CSO de surveillance optique, Ceres de renseignement électromagnétique, et Syracuse de communications militaires, rappellent Les Echos. En juillet 2019, la ministre des Armées, Florence Parly, a aussi annoncé un nouveau programme d'armement nommé « Maîtrise de l'Espace », pour intégrer deux volets : la surveillance de l'espace et la défense active dans l'espace.

By: Jaroslaw Adamowski WARSAW, Poland — The Croatian government has canceled its decision to purchase used F-16C/D Barak fighters from Israel, the Defence Ministry said in a Jan. 14 statement. The move follows a recommendation by the Croatian Defence Council that authorities relaunch the procurement step of its fighter jet acquisition program, set up to replace the country's outdated Mikoyan MiG-21 fighters. The council is comprised of President Kolinda Grabar-Kitarovic, Prime Minister Andrej Plenkovic, and a number of senior government, parliamentary and military officials. After a thorough analysis of the canceled procurement, Plenkovic's cabinet will “define a new model” of acquiring fighter jets for the Croatian Air Force, the prime minister said. Prior to the cancellation, Croatian Defence Minister Damir Krstičević said in a statement that “Israel has ... unfortunately officially informed the Ministry of Defence that it is unable to receive the adequate [third-party transfer] approval for the delivery of Israeli F-16 Barak aircraft to the Republic of Croatia.” Earlier this month, the Croatian government said it had given “Israel a deadline on its capability to deliver the aircraft offered at the international tender” and that Israel was “responsible for obtaining the approval from the United States for the supply of the aircraft.” Croatian officials have told local media the U.S. government accused its Israeli counterpart of unfair competition in the tender, in which the U.S. had offered Croatia secondhand F-16s. Other bidders included Greece, which offered used F-16s, and Sweden, which offered JAS 39 Gripen fighters. https://www.defensenews.com/air/2019/01/14/croatia-backtracks-on-decision-to-buy-israeli-jets-what-went-wrong
