Updated: 2023


The Range Radar Replacement Program (RRRP) replaces outdated instrumentation radar systems at Aberdeen Test Center, Maryland; Yuma Test Center, Arizona; and White Sands Test Center, New Mexico. This effort responds to a need defined by the Army Test and Evaluation Command to improve range tracking instrumentation while eliminating obsolescence, stabilizing operation and sustainment costs, and improving mobility and remote operations.

RRRP Block I will satisfy the Test Capability Requirements Document (TCRD) Addendum and bridge capability gaps to Block II. Block I includes a service life extension for FPS-16 (long-range, single-object tracking radars) and MPS-39 Multiple Object Tracking Radars (MOTR), as well as Modified Commercial-off-the-Shelf (MCOTS) short-, medium-, and long-range radars. Block II provides long-range MCOTS radars, which satisfy the TCRD requirements.


RRRP will provide the capability to test current and future Army weapon systems, providing critical test data to inform system development decisions and reducing the risk to operational forces prior to Fielding.
