The Naval Air Warfare Center Aircraft Division (NAWCAD) laboratories and the Anti-submarine Warfare Systems program office (PMA-264) rapidly developed
a new sonobuoy launching system over the summer and fall which was delivered this November. The new system was developed as the existing system, the S-3, was being retired. A bit of brainstorming resulted in putting two SH-60B launchers on a pallet to roll on and off from a KC-130 tanker operated by the VX-30 Air Test and Evaluation Squadron.
P-8A: Sonobuoy drop
Sonobuoys are used to detect and identify moving underwater objects by either listening for the sounds produced by propellers and machinery (passive detection), or by bouncing a sonar “ping” off the surface of a submarine (active detection). They usually float, or have at least some part of them that does. Specialized sonobuoys can also detect electric fields, magnetic anomalies, and bioluminescence (light emitted by microscopic organisms disturbed by a passing submarine); as well as measuring environmental parameters like water temperature versus depth, air temperature, barometric pressure, and wave height.
Sonobuoys are generally dropped from aircraft or helicopters that are equipped with a means to launch them, and electronic equipment to receive and process data sent by the sonobuoy. They can also be launched from ships. This entry will discuss some of the new sonobuoys in use, and cover related contracts.

It may yet be a decade or two before the U.S. has an appetite for another “generation” increment for its fighters, but Boeing and Northrop Grumman are hungry now. Northrop is
touting its new design teams dedicated to generating capabilities for the Navy and Air Forces future wish lists. The little information about their initial efforts indicate that it is oddly close to Boeing’s own requirements appetizer, which sported a flying wing design and preceded Northrop’s announcement by more than a year.
The flying wing focus may be a product of these airframes being quite similar to existing development work done for stealth fighter UAV programs, which have featured the more stealthy wing designs.
After seeing how chummy the service branches became in creating a joint strike fighter, Northrop is bowing to current service desires and employing two independent teams to ensure that both the Navy and Air Force can dream big without design compromises.
Some F/A-XX work was generated back in April 2012, when the Navy asked contractors for information about F/A-18E/F Super Hornet and Growler replacements – an early indication that the F-35 was not going to be all things to all services.
One interesting feature, at least in Boeing’s theoretical offering, is that the fighter can be flown by wire – still a politically charged feature in several ways. Pilots have been skeptical of unmanned fighters, such as the UCAS-D/N-UCAS/UCLASS program. The subsequent UCLASS project has been watered down by the Navy, with its role limited to surveillance type activities it is thought in order to preserve the more kinetic jobs for manned aircraft like the F/A-XX.

By the time 2005 drew to a close, Canada was pursuing UAV deployments on 3 fronts. The RQ-11 Raven’s early performance in Afghanistan led to purchases of soldier-portable mini-UAVs, which would be joined by older Sperwer tactical UAVs already in inventory. Canada’s Air Force was also crafting a multimillion-dollar plan to purchase the Joint Unmanned Surveillance Target Acquisition System (JUSTAS), for fielding around 2010.
Canada’s defense procurement system rivals India’s for inefficiency, so it isn’t completely surprising that nearly a decade of effort has produced essentially nothing.

Latest updates[?]: Poland joins AGS; 1st fuselage complete; Global Hawk Block 40 flies 1st combat mission; Canada may contribute to operating costs; Infrastructure approved for Sigonella; Additional Reading sections updated.
What is it good for?
The Alliance Ground Surveillance (AGS) program began in 1995, and it has taken a very long time. Its MoU was late, its contract will be both late and smaller in scope, and it won’t meet even a revised 2012 – 2014 fielding window. At long last, however, one can be assured that it will exist. This is DID’s in-depth FOCUS Article covering the AGS program, from its platforms to its program structure to its long-awaited contracts.
The original AGS plan involved an Airbus A321 counterpart to Northrop Grumman’s E-8C Joint Surveillance Target Attack Radar System (J-STARS), a Boeing 707 derivative whose powerful ground-looking Synthetic Aperture Radar (SAR) offers American commanders combat-changing battlefield surveillance and communications. AGS would be a pooled NATO asset, adding 7 RQ-4B Global Hawk UAVs and dedicated ground stations to complement the manned planes. It has since been reduced to just 5 RQ-4 Block 40 Global Hawk UAVs and dedicated ground stations, but could expand again if countries decide to make some of their national surveillance assets part of the program.
