Latest updates[?]: Major battery contract to power the railgun's capacitor bank.
Back in March 2006, BAE Systems received a contract for “design and production of the 32 MJ Laboratory Launcher for the U.S. Navy.” Some hint of what they are talking about can be gleaned from the name. BAE isn’t the only firm that’s working on this program, which the US Navy sees as its gateway to a game-changing technology. The project is an electro-magnetic rail gun, which accelerates a projectile to incredibly high speeds without using explosives.
The attraction of such systems is no mystery – they promise to fire their ammunition 10 or more times farther than conventional naval gun shells, while sharply reducing both the required size of each shell, and the amount of dangerous explosive material carried on board ship. Progress is being made, but there are still major technical challenges to overcome before a working rail gun becomes a serious naval option. This DID FOCUS article looks at the key technical challenges, the programs, and the history of key contracts and events.

NH90: TTH & NFH
The NH90 emerged from a requirement that created a NATO helicopter development and procurement agency in 1992 and, at almost the same time, established NHIndustries (62.5% EADS Eurocopter, 32.5% AgustaWestland, and 5% Stork Fokker) to build the hardware. The NATO Frigate Helicopter was originally developed to fit between light naval helicopters like AW’s Lynx or Eurocopter’s Panther, and medium-heavy naval helicopters like the European EH101. A quick look at the NFH design showed definite possibilities as a troop transport helicopter, however, and soon the NH90 project had branched into 2 versions, with more to follow.
The nearest equivalent would be Sikorsky’s popular H-60 Seahawk/ Black Hawk family, but the NH90 includes a set of innovative features that give it some distinguishing selling points. Its combination of corrosion-proofing, lower maintenance, greater troop or load capacity, and the flexibility offered by that rear ramp have made the NH90 a popular global competitor.
As many business people discover the hard way, however, success can be almost as dangerous as failure. NH Industries has had great difficulty ramping up production fast enough to meet promised deliveries, which has left several buyers upset. Certification and acceptance have also been slow, with very few NH90s in service over a decade after the first contracts were signed. Booked orders have actually been sliding backward over the last year, and currently stand at 474 machines, on behalf of 14 nations.
