Larger Firescout UAS. Too Big for the Coast Guard?

For quite some time the Coast Guard has been planning on putting helicopter like Unmanned Aerial Systems on their ships. Interest has centered on the Navy’s MQ-8B Firescout. I suspect the hangar designs for the National Security Cutters and Offshore Patrol Cutters were based in part on the size of the MQ-8B.

Now DefenseNews is reporting the Navy is announcing they will stop production of the 3,150 pound max gross weight “B” model and go to a much larger 6,000 pound max gross weight “C” model based on the Bell 407 Jet Ranger. This aircraft is not only approaches the size of the H-65, it is actually longer.

The larger MQ-8C certainly offers advantages over the smaller “B” model, including the ability to maintaining 24/7 surveillance with only three flights a day. The Navy believes they will be able to deploy three on their frigates and two in addition to an H-60 on the LCSs. The NSCs probably have adequate space, but it is unclear if the space provided for in the specifications for the Offshore Patrol Cutters will allow them the emulate the LCSs’ aviation facilities or if they will be able to carry even one of these larger UAS in addition to a manned helicopter.

UAVs, Let’s Try This One

Here is a UAV that is already in use by the Navy. The ScanEagle, is so small it could operate routinely from the Webber Class WPCs.

Wing Span 10.25 ft (3.12m)
Length 6.5 ft (1.98m)
Max Take Off Weight 44-48.5 lb. (22 kg)
Max speed 80 knots
Cruise speed 50 knots
Ceiling 10,000 ft
Max endurance: 15 hours

In it’s “dual bay” configuration the sensor package can include a synthetic aperture imaging radar in addition to video. It can use standard diesel fuel, but it won’t use much since the engine is less than two horsepower.

It was reportedly used during the Maersk Alabama piracy incident in April 2009 (the first of three times pirates attempted to take the ship).

I think its worth a closer look, like perhaps a deployment on a 210.
