گونه های شناخته شده
Oxcart
Classified designation given to the A-12 project by the CIA
Senior Crown
Classified designation given to the SR-71 project
A-11 Archangel
Lockheed's internal designation for its proposal to meet the CIA's high-speed reconnaissance aircraft requirement
A-12
Original design concept for a high speed bomber/interceptor, but built as a single-seat recon/strike platform, based on the A-11 design but with improvements to lower the radar cross section; 13 built (5 lost)
M-21
Originally intended as A-12 airframes but modified during construction with a second seat for an officer to operate the D-21 drone, the new designation refers to the aircraft's role as a mothership (M-21) to launch the daughter (D-21) and increase reconnaissance range; 2 built (1 lost)
YF-12A
Initially designed as an interceptor prototype equipped with a Hughes AN/ASG-18 pulse-Doppler radar in the nose and tandem weapons bays for AIM-47 air-to-air missiles, later used by NASA as Mach 3 research aircraft; 3 built (2 lost)
F-12B
Proposed production model of the YF-12A to serve as a USAF high-speed interceptor; cancelled
YF-12C
A-12 airframe modified with increased fuel capacity and other refinements to test many of the improvements incorporated into the SR-71; 1 converted
RB-12
A proposed reconnaissance bomber variant that reached the mockup stage before being cancelled
RS-12
Proposed strike model
B-12 or B-71
Proposed dedicated bomber variants
RS-71A
Original designation for the dedicated reconnaissance model
SR-71A
Definitive reconnaissance model with aerodynamic refinements, improved airframe, greater range, and fitted with advanced surveillance equipment; 29 built (11 lost)
SR-71B
Two-seat trainer with a separate raised cockpit for an instructor pilot; 2 built (1 lost)
SR-71C
Two-seat trainer rebuilt from a YF-12A structural test model and incorporating parts from other crashed airframes, built to replace one of the SR-71B trainers that was lost, later used by NASA; 1 converted
