U.S. Coast Guard Releases RFIs for Two Upcoming Cutter Boat Acquisitions

The U.S. Coast Guard recently released requests for information (RFIs) in support of two upcoming cutter boat acquisitions.

On Nov. 7, the Coast Guard released an RFI in support of the over the horizon V (OTH-V) acquisition. On Nov. 18, the service released another RFI in support of the long range interceptor III (LRI-III) acquisition.

The OTH-V boats will deliver boarding teams to vessels of interest while the LRI-III will help cutter crews extend their interdiction range. Both vessels will be capable of performing missions that require projection of the service’s capabilities beyond the parent cutter. The boats will operate during both day and night in a spectrum of climates, weather conditions and sea states.

The planned OTH-V is a standard configuration boat up to 26 feet long, which will operate with the major cutter fleet. The anticipated scope of the contract is near 200 boats scheduled to be delivered over a 10-year-period. The deadline to submit responses is Dec. 16.

The planned LRI-III Is a standard configuration boat up to 33 feet long, which will extend the national security cutter’s mission reach. The anticipated scope of the contract is about 15 boats scheduled to be delivered over a 4-year-period. The deadline to submit responses is Dec. 19.
