I just wonder why kinda cancelled for a while MPUAV is making appearance in video...

Probably just showing other UCAV concepts (they also show the VTOL UCAV landing on an LCS flight deck at 1:57).  This LM UCLASS seems much smaller than the X-47B.  ???

That's the first thing I thought about when I saw the video.  Though the video is no tell sign, but I venture to say that MPUAV may have gone black.  Just imagine the sensitive nature of a low rcs reconnaissance uav launched stealthily from a silent submarine to monitor hot spot around the world.  I think that if it gone black, it may have gone black after Lockmart demonstrated the technological feasibility of launching such a vehicle to break free of the water surface and recovering it.

That hump on top of the UCLASS is probably for SATCOM; - or a place holder for "R2-D2"?  :D

If it had gone black, it wouldn't be showing up in unclassified Skunk Works videos.

Exactly.  They just added stuff from other programs in the past (that made it to hardware or not).  It's not like they're still launching D-21s from Blackbirds.

What I meant is that the concept of launching a stealthy uav from submarine has gone black in the form of another program, but not the actual cormorant MPUAV program.  Cormorant was a white world program that proved its point as much as it was over.

Lockheed Martin's Skunkworks on Tuesday unveiled the company's entry in the Navy's Unmanned Carrier Launched Airborne Surveillance and Strike competition. The company is touting the design, which bears a resemblance to its classified Air Force RQ-170 Sentinel remotely piloted aircraft, as leveraging its experience on other unmanned systems as well as the F-35 to achieve "maximum reuse of hardware and software" toward lowering cost and risk. The unnamed design, which features folding wings for carrier duty, embodies "multi-spectral stealth," said the company.
 
A video on Lockheed Martin's website describes the vehicle's mission as performing intelligence, surveillance, and reconnaissance as well as strike, communications relay, and aerial refueling. The Navy wants to get the UCLASS into production by 2016, and has identified Boeing, General Atomics, Lockheed Martin, and Northrop Grumman as companies capable of doing the work. Navy officials said they plan to take all four companies into a design phase. Northrop Grumman has been flying its X-47B as a UCLASS technology demonstrator. The UCLASS is the descendant of the joint Air Force-Navy program to develop a new class of combat RPAs, which included Boeing's X-45 demonstrator. The Air Force withdrew from the project to pursue its next-generation bomber.
--------------------------------------------------------------------------
Bolding mine - If you had a super stealthy platform with DATS which - from a video on the F-35 news thread - can detect rocket and artillery from hundreds of km away opens up a very interesting concept of operations.
 
UCLASS cruising undetected relaying this information back to a platform with long range stealthy strike missiles (well outside radar range and hopefully someday hypersonic missiles) would be a game changer. One UCALSS with 24 hour persistence married to an SSGN or a Burke with SM-III land attack missiles (although these may never be built) JASSM-ERs, cruise missiles or one day a RATTLRS or X-51 type system and two platforms could dominate a huge swath of territory.

Looking at the recent image posted of the Lockheed UCLASS: deployed spoilers on the wing upper surface and the split slot deflectors on the port and starboard wing panels, I would call their landing on an aircraft carrier "full commitment".  How are you going to waive off a missed landing when you are dumping lift from these control effectors (read kinetic energy)?  They must have enough confidence in their proprietary autopilot system to not be concerned about a missed trap.

"More UCLASS details from Lockheed"

Lockheed Martin is revealing additional details about its submission for the US Navy's Unmanned Carrier Launched Surveillance and Strike (UCLASS) aircraft programme saying it has already built a full-scale mock-up of the flying wing design.

"We have a full-scale mock-up," says Robert Ruszkowski, Lockheed's director of UCLASS programme development. "That's been a good engineering tool to look at fit checks."

Thumbnail image for LM-UCLASS_AlongCoast-12000.jpgFor its concept, the company's Skunk Works design team has selected a flying wing configuration because it is particularly well suited for the missions that the UCLASS is expected to fly.

"There is nothing inherently unique about a flying wing, but we have a lot of experience with them," Ruszkowski says.

The flying wing's combination of aerodynamically efficiency, potential for very low signatures and structural simplicity make it ideal for an application like the UCLASS, he says. The design would allow the aircraft to be adapted to operate against a broad swath of threats ranging from permissive airspace to the anti-access/area denial environments. "We've got the right shape for that, we've got the right materials from the [Lockheed] F-35 that can be readily leveraged," Ruszkowski adds.

While the Lockheed UCLASS has the range and persistence to fly deep into enemy territory, it does not have the weapons payload of a true long-range strike platform like the old Grumman A-6 Intruder. "We think there is an element of the mission set that might be for long range operations, but it is truly not for large payloads at long ranges," Ruszkowski says. "Trying to keep the system affordable, this will not be anywhere near a replacement for an A-6 from a strike perspective."

Because flying wings are structurally simple, they are also easier to manufacture, which helps the design to be affordable. "There is not as much tooling associated with say a flying wing compared to a more conventional design," Ruszkowski says.

Lockheed also plans on reusing as much existing hardware as possible on its UCLASS design--that might even mean adapting equipment such as the aircraft's landing gear from another platform.

The company is also designing its UCLASS concept to have open architecture avionics not only so that existing computer hardware can be reused, but it would also allow the USN to modify the sensor payloads easily. "The navy has made it clear they would like to have the ability to put new sensors or new mission systems onboard UCLASS over time," Ruszkowski says. "Obviously open architecture facilitates that."

From what specifications the navy has released, it is apparent that the service is focusing in the interfaces for the various sensors and communications gear--which suggests an open architecture design will be required.

Lockheed has also worked hard to make sure one operator can "fly" multiple aircraft, Ruszkowski says. The operator would control the aircraft by exception, which means he or she would only directly intervene in the operation of a particular UCLASS air vehicle if something of particular significance were to be occurring. By and large, the Lockheed UCLASS is designed to operate as autonomously as practical given navy operational doctrines and rules of engagement, as well as air traffic management procedures.

TAGBOARD, without the spoilers the engine thrust setting during the approach is so low that spoolup time gets too long to satisfy the waveoff criteria. Spoilers retract immediately in such case and engine needs less time to get to max.
