The War Zone (TWZ) reports on a new NAVAIR contract for Counter UAS systems.
See the four fixed radar antenna on top of the cab? Look familiar?
From the Company web site: RPS-42 is an S-Band tactical hemispheric air surveillance radar system. It is a member of the non-rotating, solid-state, digital radar family Multi-mission Hemisphere Radar (MHR), developed by RADA Electronic Industries Ltd.
The RPS-42 is a pulse Doppler, software-defined radar platform, that can detect, classify and track all types of aerial vehicles – including fighters, helicopters, UAVs, transport aircraft, etc. at tactical ranges. A single radar platform provides 90º azimuth coverage. Hemispheric coverage is achieved when four radars are employed as a system. Mobile or stationary, the system can be integrated with any C⁴I system and other radars and sensors. The software is able for On-the-Move (OTM) Operation. The radar can operate either as a stand-alone or as part of a large-scale surveillance system.
The Antenna is an Active Electronically Scanned Array (AESA) based on Galliumnitrid (GaN) Amplifiers. Its diameter is 50.4 cm, the max width is 16.5 cm.
The achievable range for detection of the smallest drones (known as Nano UAV) is 3.5 km.
Looks like they or close cousins are on PATFORSWA cutters. (Click on the photo below to enlarge.) They are on the mast.

The TWZ post has a bit of cost comparison as well.
The laser-guided rockets are modular and low-cost, with the guidance section designed to slot in between existing standardized 70mm warheads and rocket motors. The unit cost of the APKWS II guidance section is around $25,000, with the warhead and rocket motor together typically only costing a few thousand dollars more depending on their exact types, according to Navy budget documents. For comparison, the cost of a single Coyote Block 2 interceptor, another counter-drone weapon currently deployed to help protect U.S. Forces in the Middle East, is reportedly roughly around $100,000. Current generation Stinger short-range heat-seeking surface-to-air missiles, which include new features to improve their effectiveness against drones, have a unit cost of around $400,000.
For comparison, an Alamo round of 57mm costs about $29,500.
