48 SFS Overhead Gunner Protection Kit (OGPK) Salient Characteristics

This document outlines the salient characteristics for an Overhead Gunner Protection Kit (OGPK) required by the 48th Security Forces Squadron at RAF Lakenheath. The OGPK is designed as an aftermarket protective system installable onto existing Gunner Protection systems mounted on Joint Light Tactical Vehicles (JLTVs) currently manufactured by Oshkosh Defense. The kit must feature a reinforced overhead structural cage and restraint system constructed from a minimum of 3/8-inch steel, with two 12-inch by 12-inch windows fitted with transparent ballistic glass. The system must rigidly bolt directly to the JLTV's pre-existing structural frame to ensure gunner safety during vehicle rollovers and must include all necessary high-strength, vehicle-grade mounting hardware and detailed step-by-step installation instructions. The central design principle requires the kit to be completely unobtrusive, ensuring no obstruction to the weapon system, gunner freedom of movement, or access to critical equipment.

The procurement specifies a total of 47 OGPKs to be delivered, consisting of 25 units in Green and 22 units in Tan. All units must be delivered to the 48 SFS S4 Warehouse Building #1027, RAF Lakenheath, Brandon, Suffolk, IP27 9PN, with coordination required with the 48 SFS Point of Contact. The document is revision 0003 dated 21 July 2026.
