RfP for Services/Textron’s Aerosonde sUAS

Seapower, a Navy League Magazine and web site, reports, the Coast Guard issued a Request for Proposal on February 7, for “Indefinite Delivery Indefinite Quantity Competitive and Unrestricted Commercial Services Combined Synopsis/Solicitation for Unmanned Aircraft Systems for National Security Cutters (NSCs) for the United States Coast Guard.” Proposals are due by March 9. (Pretty quick turn around.)

In particular they identify two competing systems, the Scan Eagle from Insitu and Textron Systems Aerosonde sUAS. We have been talking about the Scan Eagle for almost seven years. Also the Coast Guard has been using Scan Eagle operationally, but since we have not talked about the Aerosonde I thought, perhaps we should take a look.

There is a pdf brochure on the Aerosonde here.

The Aerosonde is a bit bigger than the Scan Eagle, but if a larger aircraft is needed then Insitu has the option of offering the RQ-21 Blackjack which is in the Navy’s inventory. 

For a rough comparison, Scan Eagle has a max Take Off Weight 44-48.5 lb. (22 kg), Aerosonde has a max TO weight of 80 lb (36.4 kg), and the RQ-21A Blackjack a max TO weight of 135 lb (61.4 kg).

“The U.S. Coast Guard customer has expressed unique technology and operational requirements in its Small Unmanned Aircraft Systems (SUAS) RfP,”  so we are not simply going to buy what the Navy already has. Using the usual optical systems is like looking through a straw. I expect the Coast Guard is going to want an area search capability, radar or perhaps ViDAR.

Figuring out how best to use these is going to be an interesting Operations Research problem. What search pattern? at what altitude? How far out can we fly these and still communicate and have the cutter provide sense and avoid to prevent a mid-air?
