Teal Group Corporation's overall, cumulative military electronics Manufacturer Market Shares Forecast for the next ten years (FY18-FY27) shows 33.1% of the total market will be available for new primes (worth a whopping $161.0 billion), when considering that continuing production for most current programs is locked up by the incumbent. Note that a much higher share than this 33.1% will be available for subcontractors.
Production of the AN/ALQ-135 has ended for US aircraft, but updated systems were in production for South Korea’s F-15Ks through about 2013 (Singapore turned to Israel for its F-15SG’s EW suite). The F-15 has been among the most successful US fighter programs, and the sale to South Korea was hugely important for its future. The F-15K/SG rejuvenated the aircraft, with new systems, weapons, and sensors. Also, both countries have al-ready bought more planes, as a 40 or 12 aircraft force is not a sustainable minimum for the long run.
