Karman Space & Defense, a leader in the rapid design, development and production of critical, next-generation system solutions for launch vehicle, satellite, spacecraft, missile defense, hypersonic and UAS customers announced it has acquired ISP, a leader in specialty energetic propulsion technologies including small boost motors and solid propellant gas generators for the rapidly growing UAS, UAS intercept and rocket-assisted takeoff systems markets. The transaction closed on May 28, 2025.
Founded in 1983 and based in Cedar City, Utah, ISP has developed a proprietary portfolio of propellant formulations and tactical motor configurations, with proven flight heritage across a number of high-priority U.S. Department of Defense (“DOD”) programs. ISP designs, tests, qualifies and manufactures small-diameter energetic and propulsion systems to meet mission requirements for distance, total impulse, peak thrust and burn time. With the required engineering and manufacturing capabilities to take a product from concept-to-production, ISP is a proven partner to prime customers in delivering integrated energetic and propulsion systems, with more than 40 years of flight heritage.
