It's accepted that the top speed of the SR-71 was likely around Mach 3.5. The Mach 3 records were just for show, and pilots have said that even at Mach 3 when they pushed the throttle forward, it just went.
This article also says that the SR-72 will use "a dual-mode engine that combines turbine and ramjet technologies." The SR-71 already did that.

The Mach 3 records were just for show, and pilots have said that even at Mach 3 when they pushed the throttle forward, it just went. FWIW the official record is Mach 3.3, Air & Space/Smithsonian reported that it'd been clocked at 3.4 by USAF, and Brian Schul claimed to have exceeded 3.5 during evasive manoeuvres. Mach 3 was never claimed to be anywhere its limits. Hell, the design / cruise speed was 3.2.
