The latest in US army aviation got off the ground for the first time late on 7 August, when the Long Endurance Multi-Intelligence Vehicle (LEMV) flew for 90 minutes over the Lakehurst Naval Air Station, New Jersey. Lead contractor Northrop Grumman boaststhat it has “successfully developed the world’s largest, most-persistent lighter-than-air optionally piloted aircraft”.
Yes, it’s an airship, but no ordinary one. It’s a hybrid vehicle, which gets lift not just from its helium tanks, but also from its modest wings and its four diesel engines. The army wants the roughly 100-metre LEMV to hover up to 6 kilometres over the battlefield carrying 1100 kilograms of cameras, sensors and communications gear for up to three weeks without landing. That’s far longer than today’s heavier-than-air robotic aircraft can stay airborne.
The big allure of airships for the army is their potential to cut the costs of gathering intelligence, surveillance and reconnaissance data. Sending a fighter jet on such a mission can cost $10,000 an hour, but Northrop says $20,000 could keep the LEMV in the air for three weeks. However, building the first one cost $154 million.
Both the army and air force issued contracts for surveillance airships two years ago, but in May the air force cancelled its programme. LEMV’s first flight was a year later than initially planned.
is it me or is there something vaguely familiar about this design?

interesting article, but no sourse, plaigirized.

nice red herrings but spelling has nothing to do with the issue…
…an interesting article with no attribution given.
i know paligirizing is common in the “newz” section but as a reader of the site its unacceptable

and since I see more typos, should know im on a phone and could care less about a grammatical error/typo when understanding is clear. Why should I bother when you dont take care either

Touché !!!
Postin’ from a phone is a tad tedious !

over the battlefield indeed! 1 little rocket and poof, its Hindenburg all over again! Oh, I see, it will have stealth paint so it is invisible. Or, better yet, a cloaking device.
