Hail Hydra!

It's big, it's fast, it's sneaky, it's deadly, and it's unmanned.  The U.S. Defense Advanced Research Projects Agency's (DARPA) proposed "Hydra" unmanned submersible (also know as an unmanned underwater vehicle (UUV)).

The U.S. Navy currently deploys smaller UUVs or unmanned aerial vehicles (UAVs) from surface ships or submarines for a variety roles, including removing line of sight limitations, remote attacks on targets, and detailed imaging of potential targets.

But flying and diving drones are limited by their range to within a certain radius of the manned fleet.  And the drones could hypothetically attract attention back to the manned fleet, tipping the enemy off on their location.  Last, but not least, the use of larger manned ships greatly increases the cost of an operation.

DARPA warns:

The rising number of ungoverned states, piracy, and proliferation of sophisticated defenses severely stretches current resources and influences U.S. military capability to conduct special operations and contingency missions.

Hydra looks to eliminate that, serving as a mini underwater carrier for both UUVs and UAVs.  Like naval submarines, it would be able to travel days on end, allowing remote operations with smaller drones in areas where there are no nearby manned vessels.  The new Hydra craft will be designed to perform missions (via its UAV payloads) in three arenas -- underwater, on the surface, and in the air.

DARPA will officially kick off the effort to build Hydra at an Aug. 5 event at Johns Hopkins University in Laurel, Mary.

The government agency is seeking private sector contract bids to first design components, build those components, integrate them into subsystems, and finally merge those subsystems into a working prototype.  Among the necessary subsystems include the ballast system, energy, communications, command and control, propulsion, a modular UAV/UUV carrier-style storage assembly to accommodate different drone payloads, and measures for long-duration submerged operations.

The mothership must be able to dock with returning drones to recharge/refuel them and to pool their collected data.  The craft must be able to operate independently in shallow coastal waters and harbors for extended periods, maintaining constant secure communication with distant operators.  It must be able to deploy all of its drone payloads without surfacing, and be able to maintain communication with the drones -- including aerial units -- while staying underwater.  And ideally it needs to be able to retrieve the drones for reuse.

Currently Raytheon Comp. (RTN), one of America's largest defense contractors, and AeroVironment, Inc. (AVAV), one of the largest dedicated drone makers, have developed prototypes of a "Switchblade" launching system, which deploys a UAV which takes off out of a launcher payload which floats to the surface after being deployed from a submarine.  Retrieving data (communicating with) that flier and possibly retrieving it for later reuse will be tricky to accomplish, though.

The The U.S. Navy Research Lab has been developing a similar aerial "mothership" drone called "Tempest", which launches smaller mini-drones call "Cicadas".

Get real. Most anti-American sentiment depends on the perception that the US unfairly influences politics beyond its borders using means that are, at best, hypocritical and, at worst, illegal under international treaties.

There are literally hundreds of examples. War in Iraq? Not sanctioned by UN. Illegal renditions? Ignore local law during transport. Torture and military trials? They contravene Common Article 3 of the Geneva Conventions. Treatment of non-citizens? Everyone knows by now that non-US citizens within the US are not protected by the US constitution...if you believe certain extremist Republicans and ignore the Bill of Rights.

All America needs to do is stop listening to politicians who use fear and ignorance to force unwise actions like propping up dictators in the Middle East (e.g. Egypt before its revolution which has done WONDERS for our reputation - both sides hate us now).

We don't really need to fear terrorists. We just need to stop creating them. We don't need to be ignorant. We can force Congress to shut down secret laws made in secret courts by judges elected unchallenged by a Supreme Court head without oversight and who pass secret applications for suveillance 100% of the time (barring one withdrawal and a couple of typo fixes...).

The worst part is that America DESERVES the hate it gets. It's doing it to itself with every bomb, plane, military aid dollar, diplomatic visit to a dictator, and word spoken by the morons in Congress that the rest of the world notices.

A sane nation would learn from its mistakes, not repeat them to infinity in a sad comedy.

America can be SO much better...
