Manufacture of spare ALR-56M radio frequency line switches, 5865-01-324-7734EW

The U.S. Air Force Sustainment Center awarded a $125,940 delivery order to Planar Monolithics Industries, Inc. (PMI) on September 30, 2025, for the manufacture of spare ALR-56M radio frequency line switches (National Stock Number 5865-01-324-7734EW). This delivery order, with a completion date of April 30, 2026, represents the initial order under a larger five-year indefinite delivery contract valued at $1.26 million that PMI was simultaneously awarded. The ALR-56M switches are components of the Advanced Radar Warning Receiver system installed on F-16 Blocks C/D and C-130J aircraft, supporting critical air defense capabilities. PMI, a Frederick, Maryland-based manufacturer of high-reliability radio frequency and microwave components, was selected without set-aside designation, competing on the basis of its established expertise in defense electronics and prior experience delivering similar components to the Department of Defense. The firm has maintained federal government registration since 2001 and holds an extensive prime contract portfolio across Naval Sea Systems Command, Air Force Sustainment Center, Defense Logistics Agency, and other major defense agencies.

The underlying indefinite delivery contract structure provides for an 18-unit base year requirement with 20 units annually in four subsequent 12-month ordering periods, establishing a framework for sustained production of these critical radar system components. PMI's selection reflects the contractor's demonstrated capabilities in producing sophisticated radio frequency switches and amplifiers for naval, air force, and defense logistics applications, complemented by its active role as both a prime contractor and subcontractor to major defense primes including Lockheed Martin Corporation, BAE Systems, and Leidos Inc. This award supports the Air Force's sustainment objectives for legacy fighter and transport aircraft while contributing to the broader defense industrial base for specialized microwave and radio frequency component manufacturing.
