As founder and former CEO of Gulfstream, Allen E. Paulson understood his customers and their need to minimize travel time and maximize comfort and operating flexibility. J. Michael Paulson founded Supersonic Aerospace International LLC (SAI) to fulfill his father’s vision: to make quiet supersonic flight a reality. The Quiet Supersonic Transport (QSST) is the embodiment of Allen E. Paulson’s lifelong dream.
QSST’s design is the culmination of 3 ½ years of work performed at a cost of nearly $25 million. Under contract to SAI, Lockheed Martin’s famed ‘Skunk Works’ designed an aircraft that can be built, can be certified and can satisfy all established (and proposed) sound and environmental regulations. QSST will be capable of supersonic flight without an objectionable sonic sound level, virtually eliminating takeoff sound objections that limited the now-retired Concorde. In addition, QSST will operate from 8,000 foot runways, allowing it to utilize nearly all of the world’s business airports.

Actually yes... The B-2 is apparently a very silent plane...
Greater efficiency helps the B-2 travel long distances in a short period of time. It's not the fastest craft around -- the military says it's high subsonic, meaning its top speed is just under the speed of sound (around 1,000 ft/sec or 305 m/s) -- but it can go 6,900 miles (11,000 km) without refueling and 11,500 miles (18,500 km) with one in-flight refueling. It can get anywhere on Earth on short notice.
Maximum speed: Mach 0.85 (560 knots, 1000 km/h)

Has anyone though that this may already be flying on some military aircraft?
