Lockheed Martin video animation from 2001 showing its concept for a US Navy carrier-based Multi-Role Endurance (MRE) Unmanned Aerial Vehicle (UAV).
Anyone know what LOCAAS stands for?
"Lokaas" is Dutch for "bait", which seems more than a coincidence.

[edit]
Quick internet search revealed: Low-Cost Autonomous Attack System

The "autonomous" bit is always interesting in unmanned warfare. If everything becomes unmanned in the future, we can leave all fighting to robots and it'll just be a technology p*ssing contest, where obviously the richest country wins. Afghanistan shows a different reality though.

Navy orders study on UCLASS concepts By Philip Ewing Monday, June 27th, 2011 2:30 pm 

The Navy wants an Unmanned Carrier-Launched Airborne Surveillance and Strike aircraft — or UCLASS — to fly off its carrier decks by 2018, and to that end it has awarded Boeing a contract to study just how it can get there, the aerospace company said Monday. Basically, from Boeing’s announcement, it sounds as though the Navy wants to lay down as much groundwork as possible to prove that it’ll be possible to take an aircraft, get it out to sea, on the cat, into the air and then trap it back on board.
From Boeing’s announcement:
Boeing has received a $480,000 study contract from the U.S. Navy to support pre-Milestone A activities including development of a concept of operations, an analysis of alternatives, and an investigation of potential material solutions for the Navy’s Unmanned Carrier-Launched Airborne Surveillance and Strike (UCLASS) program.
“The Navy wants UCLASS in the fleet in 2018,” said Jimmy Dodd, vice president, Advanced Boeing Military Aircraft. “Boeing has been delivering carrier-based aircraft to the Navy since 1925. With Boeing’s broad experience in unmanned systems and rapid prototyping, and nearly 90 years of carrier-based aircraft know-how, we are prepared to meet that schedule to support the mission and requirements the Navy establishes. This contract is the start of that.”
The UCLASS system will consist of an air segment, a connectivity and control segment, a Carrier Vessel-Nuclear (CVN) segment (launch and recovery), and a systems support segment. The work on the eight-month contract, according to the Navy’s Broad Agency Announcement, will conceptually demonstrate that a UCLASS system can provide a persistent CVN-based Intelligence, Surveillance & Reconnaissance and strike capability supporting carrier air wing operations in the 2018 time frame.

Meet Boeing’s New Carrier-Launched Drone Design

Well, it looks like ths might be Boeing’splanned bid for the Navy’s next strike fighter, (after JSF, anyway) known as the Unmanned Carrier Launched Airborne Surveillance and Strike (UCLASS).
I just took this picture, showing a drawing of an advanced looking-drone under the UCLASS name, at Boeing’s booth at the Navy League’s annual Sea, Air, Space conference in National Harbor, Md. This was the first I’d seen of anything hinting at Boeing’s planned bid for the Navy’s UCLASS effort which hopes to have a fighter-size, air-refuelable, stealthy strike drone flying from carrier decks by the end of the decade. UPDATE: Boeing officials tell me that is is simply a concept drawing and not a final design.
Remember, Northrop Grumman is likely to offer a version of its X-47B for the UCLASS contest while General Atomics is offering a version of its Predator C Avenger, called the Sea Avenger, that’s equipped to handle the strains of catapult launches and arrested landings as well as the salty sea air and Lockheed is apparently going to bid with a yet-to-be revealed design.

Sounds like they've given up on Phantom Ray.

If the above configuration is what Boeing intends to field, there will be much work in the subsonic tunnels trying to figure out why there's a pitching moment problem across the AoA range that CFD may not be catching.  It stems from the shovel shaped nose used trying to keep the planform alignment for RF LO shaping.  They may even need to change their configuration to include small canards or a tail.


Early JASSM variants dealt with this issue and added the wedges, that drop off after release and capture, on the aftbody near the exhaust nozzle.  What's more is the flight envelope for JASSM has a smaller range than the UCLASS will see - with the launches and landings on moving and carriers with turbulence, etc.  I hope the technical evaluation committee catches that problem before awarding more funding, as this will likely help drive the risk and cost up.


It's interesting how many past lessons learned are not applied by future efforts.

it just asks for V-tail like Lockheed's MREUAV/UCLASS...and then it will be looking just ...indistinguishable from last one

That's what happens when nobody communicates and everybody uses contract workers.

I share the sentiments regarding pitch authority. They might be planning to use thrust vectoring in the vertical plane to trim the aircraft.
But even this seems dicey, and i can't recall any other aircraft ever doing that. If they can pull it off, my hat's off to them.
