This federal contract award to Cortron, Inc., a small business manufacturer of rugged computer input devices, is for the supply of 10 Aircraft Track Ball Assemblies (part number SPAE20650808) to the Naval Supply Systems Command (NAVSUP) for $2,500. The award was made under a sole-source agreement, as Cortron is the Original Equipment Manufacturer (OEM) and the only known source for this specialized spare part. The contract has a one-year period of performance and was not set aside for small businesses. Cortron has a history of providing similar input devices, such as keyboards and mice, to various military and civilian agencies under both prime contracts and subcontracts with major defense contractors. This award is likely part of the company's ongoing support for the sustainment of the U.S. military's Patriot missile system and other critical defense platforms.
