This notice serves as both a sources sought notice and a notice of intent to sole source a contract with Battlespace Simulations LLC to restore non-mission-capable Portable Lightweight Designator/Rangefinder (PLDR) and Common Laser Range Finder - Integrated Capability (CLRF-IC) targeting assets to fully operational, calibrated, and deployable status. The work involves proprietary software, firmware, and optical calibration that only the original developer can provide, as the government lacks the necessary data rights. Performance is intended for the CAVE training systems capability at Expeditionary Warfare Training Group, Pacific (EWTGPAC), Naval Amphibious Base Coronado in San Diego, California. Interested parties are invited
