Marquardt RJ43 ramjet family
Marquardt RJ43 is a historical family of 28-inch ramjets developed for missile cruise propulsion. NASA identifies the family in Boeing BOMARC's two-engine cruise stage and separately documents the RJ43-MA-3 model in Propulsion Systems Laboratory tests; this entry preserves the family/model distinction.
