US Naval Institute News Service is reporting that the Navy is looking at providing better sensors, in particular a better radar, on the MQ-8C Fire Scout (the larger version).
“What’s important to us right now is making sure we have the right sensors, a good multi-function radar, some kind of passive targeting capability and the right networks to push that information to the right people at the right times.”
When the Navy finally gets around to deploying LCS to the drug transit zones, these could be very useful.
Reportedly they will provide, “…a circle of influence and sea control out to about 300 miles” although probability of detection almost certainly depends on target size and characteristics.
The radar of choice is reportedly the Leonardo Osprey 30 active electronically scanned-array (AESA) radar. This radar has no moving parts.

“Each antenna contains 256 Transmit and Receive Modules (TRM) – 25% more than that the single array on the Seaspray 7500E radar fitted to U.S. Coast Guard HC-130J Hercules search aircraft (also a Leonardo product–Chuck). The antennas, which can be used in several different modes including surface search, air-to-air and synthetic aperture radar and moving target indication, are controlled through a single processing unit which collects the data and displays it as presenting a single radar picture.”
- Class-leading maritime surveillance capability
- AESA-enabled small target mode (STM)
- Very high resolution, wide swath SAR Mapping
- Small radar cross section (RCS), low minimum detectable velocity (MDV), multi-channel moving target indication (MTI)
- Air-to-Air surveillance, track and intercept
- Instantaneous multiple mode interleaving
- Difficult target detection from high altitude
Ultimately as more of the “C” models are built, we might see them on Coast Guard cutters. There is also the possibility that as more of the larger “C” models come on line, the Coast Guard may be able to get some of the smaller “B” models. The “B” model did operate for Bertholf for two weeks.
The larger C model, with its higher speed, greater payload, better sensors, and 11+ hour endurance, would certainly be an improvement over the ScanEagle currently planned for the National Security Cutters. Whether the “B” model‘s presumably better sensors but shorter range/endurance would allow a greater effective search area compared to the ScanEagle I could only speculate, but I suspect it would also be an improvement, using perhaps two flights per day.
The National Security Cutters could certainly support both an H-65 and an MQ-8C, since they can support two H-65s. It is less clear if the OPC could support both. They reportedly can support an MH-60 or an H-65 and a UAS, but what size UAS?
These systems suggest that at some point, at least on our largest cutters, we may be able to relieve shipboard manned helicopters the routine search function.
