"Lockheed Martin's
Billion-Dollar Drone Submarine Faces Cancellation"
“And two rivals hope to profit from Lockheed's misfortune
The U.S. Navy is suspending purchases of Lockheed Martin's (NYSE:LMT) drone
minisubs, and switching to an alternative product -- probably from General Dynamics …Maybe.
…The Navy has already
spent more than $700 million on the "drone" in question, actually a
batch of 10 remote multi-mission vehicles (RMMV) designed to operate from Navy
Littoral Combat Ships on minesweeping missions. Each drone is
essentially a remote-controlled minisubmarine designed to locate and mark
anti-ship mines for later disposal by its mothership.
…15 years of development have failed to fix
problems with the minisubs, which broke down 14 times over 300 hours of testing
in recent sea trials. The Pentagon's assessment: RMMV is "not ...
operationally effective."
…Bloomberg reported earlier this week that the Navy is
considering several alternatives to Lockheed's drone. The leading contender
right now appears to be General Dynamics' Knifefish, a
similar submarine drone, which
the Navy was already planning to deploy for the minesweeping mission in 2017.
At an estimated $1 billion for 48 units, Knifefish promises to be a cheaper and
perhaps a more effective minehunter than what Lockheed Martin is offering.

That thing looks like the F-35 version of an UUV.
ReplyDeleteIt is obvious Australia would need a big submarine to operate such UUVs.

The USN is developing the Common Control System for its future portfolio of unmanned vehicles. This platform development avoids development of specific controls for each USV or UUV. CCS is originally developed for control of unmanned air vehicles.

Hi MHalblaub
ReplyDeleteAustralia should certainly invest in a torpedo tube launched UUVs if it has the cash.
Atlas Electronik is probably wise enough to realise that oversize, "large diameter" LDUUVs are ungainly and uneconomical for submarine use. Too much US Inc. via Bryan Clark campaigning for LDUUVs!

Hi KQN
ReplyDeleteThe Common Control System certainly sounds rational. Perhaps the US should use Lithium-ion Battery only propelled mine-hunting UUVs after all.
Diesel for UUVs seems to introduce un-needed, "orphan", out of sync, complexity.
