The Naval Air Warfare Center Training Systems Division (NAWCTSD), Procurement Department, at Orlando, FL, announces its intention to procure for the Naval Air Systems Command (NAVAIRSYSCOM), PMA205, the Aviation Distributed Virtual Training Environment (ADVTE) III which is the United States Marine Corps (USMC) ADVTE and Tactical Environment (Ten) Subsystem combined requirement; henceforth known as ADVTE III. ADVTE is the Marine Corps Aviation's currently implemented solution that provides integrated and networked training. ADVTE, as a persistent and integrated system-of-systems solution, currently has the capability to network various Type/Model/Series (T/M/S) Marine Corps Aviation Training System (MC ATS) training devices located across First (1D), Second (2D), Third (3D), and Fourth (4D) Marine Aircraft Wing (MAW) locations for the purposes of conducting multi-site, multi T/M/S simulated networked training missions to maintain proficiency and enhance aircrew readiness. The USMC TEn is a key software and hardware subsystem that is currently installed in nearly every USMC Aviation Training System. The USMC TEn is the current Marine Aviation's Semi-Automated Force (SAF) / Computer Generated Forces (SAF/CGF) solution and also provides the High Level Architecture interface enabling MC ATS training devices to link with other trainers for distributed mission training. The government is open to a different SAF/CGF solution for providing this capability to meet the needs of the USMC distributed and stand-alone training requirements. The current ADVTE baseline serves and provides the capability to connect multiple MC ATS training devices together at the following locations: Marine Corps Air Station (MCAS) Camp Pendleton, CA; MCAS Miramar, CA; MCAS Yuma, AZ; Marine Corps Air Ground Combat Center (MCAGCC) Twentynine Palms, CA; Marine Corps Base (MCB) Camp Lejeune, NC; MCAS Cherry Point, NC; MCAS New River, NC; MCAS Beaufort, SC; MCAS Futenma, Japan; MCAS Kaneohe Bay, HI; and Joint Reserve Base (JRB) Fort Worth, TX. By Light Professional IT Services (formerly known as Veraxx Engineering Corp) delivered the current ADVTE and current Tactical Environment (TEn) baselines. ADVTE in its current configuration was procured under multiple Delivery Orders under a single awardee indefinite delivery indefinite quantity (IDIQ) contract (N61340-22-D0002) that was competitively awarded. The current, “as delivered” ADVTE configuration is anticipated to be completed no later than FY2028. The Tactical Environment configuration and software baseline was procured under a Sole Source IDIQ contract (N61340-22-D0009) that was awarded to By Light Professional IT Services. By Light IT Services was the only company with the highly specialized knowledge and experience with the current TEn software code, and who could modify it without unacceptable delay in meeting the Government's requirement to provide full-scale integration into USMC trainers and ADVTE infrastructure at th…
