I mean come on a hyper mach sub orbital (or is the concept orbital?) bomber that can hit anytarget in the world in 3-4 hours.
How cool is that?
A 25-meter-long HyperSoar aircraft (about as long as the wingspan of a large business jet) could make a conventional takeoff from a standard runway. Using special air-breathing, rocket-based, combined-cycle engines, it would ascend to 40 kilometers-at the outer limit of Earth's atmosphere. Once there, its engines would be turned off, and it would coast up to a high point of 60 kilometers before beginning to fall back down to about 35 kilometers-well inside the atmosphere's upper level. As it descends into denser air, the aircraft would be pushed up by the increased aerodynamic lift. The engines would fire briefly, propelling the plane back into space. Outside the atmosphere, the engines shut off and the process repeats. In this way, HyperSoar would skip off the top layer of the atmosphere every two or so minutes, like a flat rock skittering in slow motion across the surface of a pond.
Inclusive of the time taken and distances covered by the ascent and descent portions of a flight, a trip from Chicago to Tokyo (10,123 kilometers) would involve about 18 skips and 72 minutes, and to travel from Los Angeles to New York (3,978 kilometers) would involve about 5 skips and take 35 minutes. (Both flights require a total of about 2,450 kilometers and 27 minutes for take off and landing.) By popping regularly out of the atmosphere and using the engines intermittently, HyperSoar would use less fuel and solve a critical problem that plagues other hypersonic aircraft designs-heat.

You all know that the f-37 is a prop for a new Jennifer Garner movie called Stealth right?

Lockheed Martin reveals future strike platform
06 June 2003
Lockheed Martin has revealed images of a stealthy, supersonic strike aircraft designed to penetrate heavily defended airspace in the initial phase of a conflict and deliver precision-guided munitions on time- sensitive and other high-value targets.
The company developed the concept, which it refers to generically as the 'long-range strike aircraft', in support of studies on future strike platforms that the US Air Force Research Laboratory (AFRL) is leading.
Although the air force anticipates operating its current bomber force of B-1B, B-2A and B-52H aircraft until 2040, it is examining complementary capabilities. It is prioritising its technology investments to be in a position to launch a next-generation strike programme around 2012-15, with the goal of fielding the system starting around 2020. The system it chooses may not be an aircraft, but rather a capability that traverses space, or some other unconventional approach.
Nonetheless, the service is examining a range of notional subsonic, supersonic and hypersonic aircraft designs as it formulates its technology roadmap.
The Lockheed Martin aircraft is a M2.0-M4.0-class system with highly swept wings and large engines, said Kevin Renshaw, Lockheed Martin's programme manager for long-range strike and advanced combat aircraft. Crew would consist of a pilot and a weapons systems operator.
The company is examining a mix of payload and range options. A payload capacity between 15,000 lb and 40,000 lb (6,802kg and 18,140kg) is envisaged, Renshaw told Jane's Defence Weekly, noting that between 20,000 lb and 25,000 lb appears to be the preferred design trade space. The concept has a notional combat radius of 3,000 miles (4,827km) without mid-air refuelling.
Renshaw said the company believes that many of the key technologies exist today for such a system but need to be refined so that they are smaller, lighter and more affordable. The company has a heritage in developing supersonic aircraft like the M2.0-class B-58 Hustler bomber and M3.2-class SR-71 Blackbird reconnaissance aircraft.
One area Renshaw highlighted for improvement is the cruise efficiencies of supersonic engines so that they require only one-half to two-thirds the fuel of existing systems.
