Crane designed, tested, manufactured, and maintained custom power supply solutions including Low Voltage Power Supplies (LVPS’s), High Voltage Power Supplies (HVPS’s), and high-powered amplifiers for weapon systems aboard airborne platforms. Their power supplies are incorporated into critical Electronic Warfare (EW) systems, including the AN/ALQ-184, AN/ALR‑56C, and AN/ALQ‑131, demonstrating high quality and exceptional reliability to function effectively for the American and Allied Warfighter. Crane has extensive experience and know-how providing power supplies for the ALR-56M requirements.

The service shall include providing obsolete parts resolution along with the necessary engineering to investigate Deficiency Reports and Material Improvement Projects (MIPs).

The ALR-56M Power Supplies must meet form, fit, function, and interface requirements as referenced in per 12P3-2ALR56M-24. However, the Government does not own the data or the rights to the data needed to compete the repair of this part. It has been determined to be uneconomical to reverse engineer the data, qualify a new source, or buy the data and/or data rights. Crane is the only source of known repair for this system and has been since it was fielded.
