First two drawings represent two Lockheed Mach 5,5 concepts from late 80s - early 90s with deep GDFW roots. Second concept has 'CL-<...>' model number.
"...A Mach 5 to 6 vehicle concepts to represent the general maximum speed achievable with hydrocarbon fuel. A typical TOGW is estimated to be 200K to 400K lbm to carry a payload over a mission radius of 3000 to 6000 nmi. This vehicle concept was based on a tandem turboramjet gas turbine engine in which the gas turbine portion of the cycle operated from takeoff to approximately Mach 3 to 4. A tandem ramburner functioned from Mach 3 to 4 to the maximum speed between Mach 5 to 6."
Third is a "...Mach 3+ vehicle concept with the maximum speed obtainable with a high speed gas turbine engine. [...]
This vehicle had a TOGW of over 300K lbm. It typically was a JP-7 fuel/thermal management system (TMS). The maximum speed is between Mach 3 and as high as Mach 4 and governed by engine compatibility, fuel/thermal management and materials/structures
technology and design."
