The First launch of a modern UCAV has taken place this week in the Atlantic.

Here's one video, there are a few other's on youtube too.

It's of great interest to me personally as I led a study into UAV Ops from QEC a couple of years ago.

I'd be more interested in the landing. Did it land back on or head to a land airfield.

With it being unmanned I can see their being lots of available methods of recovery, but im also interested to know if they have built a system (manual or auto) that is capable of the complexity of landing on a carrier.

ETA - wow this thing has a wingspan twice that of a F16 Fighting Falcon

I still think it would need a normal arrestor system to stop it on the deck.

Looks like arrested landing.

Most likely, but they have the option to ditch it and recover it, probably not viable due to the complexity of its tech and the cost. Im just not sure how they can have the latency to have the fine control to perform a carrier landing, unless they have a computer that is capable of an automatic carrier landing.

I'm sure it's designed to do just that but they are maybe not quite at the point in the programme where they are ready to try a recovery on deck.

Any reason why they didn't raise the jet blast deflector?

Hi Eric, no this time it flew to land, apparently it's due to do it's first carrier landing in July. Of course landing on a carrier is far more difficult than most other things aviators do.

Been away from my desk while composing this so I expect someone's already answered you! laugh

Edit - Dam didn't have the UCAV landing.

As an addition, about carrier landings, AIUI the F/A18E is not only capable of auto launch, but also auto recovery on a carrier. (This is from memory though, so maybe wrong).

So, the technology would be in place for it. With the jet-blast deflector, maybe as a flying wing design it produces more lift than a standard aircraft and therefore doesn't need to get to such a high speed for flight. This means it won't need such a powerful engine maybe?

Nothing behind it that the engine would melt perhaps.

Its got same plant as the F16

It may use the same core, but I'd guess it's got a bigger fan, no reheat, much lower jet velocity.

Any ideas of cost yet?

You thinking of saving up? smile
Guessing a couple of hundred million dollars?

Apparently it made its first arrested landing - on land - on 4 May.

Yes, I even posted a video of it above. hehe

This'll get your blood boiling Mojocvh, it's a demonstrator, contract was awarded to NG by the US navy for $640m'ish, and those costs have since grown to $813m.
They've only built 2 though so the unit costs are horrendous.

However, when they put such a system into production it'll costs similar to any fighter/ground attack airframe I'd have thought, without quite so high pilot training costs.

These things are now designed around autonomy, they are able to react to given situations and only need a man-in-the-loop to engage etc. You can have squadrons of them over the battlespace 24/7, with other designated to re-fuel as necessary. They'd only ever need to land to re-arm. So with that in mind, for a constant presence in a hostile environment, they're priceless.

That's actually not a bad price, seeing as you don't get much change from $100m for a 4th gen high volume jet- didn't f22s come out in the low $200s?
