F-35 being sold with promise of a hypersonic missile?
The X-51 hypersonic missile - a test missile under development - here attached to a B-52.
Is an unpublisized missile being used as a major selling point for the F-35 Joint Strike Fighter (JSF)? With constant delays and cost overruns is Lockeed Martin attempting to entice potential F-35 buyers by combining the sale with a smaller derivative of the X-51? Is this smaller missile being advertized in confidential forums as a "game changer"?
If the missile is a miniaturized derivative of the X-51 it would be a hypersonic, very advanced missile indeed. The smaller missile might be "paper" only or perhaps under US development and may not be mature until delivery of the F-35 to foreign customers from 2018-2020 onwards. Such a missile would need to be small enough to fit within the F-35's stealthy body. Hypersonic speed is generally considered Mach 5 or above.
JASSM about to hit a steel reinforced concrete target. In this case the whole missile is in the end run. But it is also possible that the warhead could detach and be rocket propelled to higher Mach speeds shortly before it hits a target.
If the missile is less advanced and more publicized it may be a version of the stealthy, turbojet, cruise missile AGM-158 JASSM (Joint Air-to-Surface Standoff Missile) that has been slightly reduced in size to fit inside an F-35. Deploying such a JASSM externally on hardpoints is considered to adversely effect the F-35's stealth profile.
The JASSM is now coming into service with the USAF and Australian Airforce (RAAF). It may be that the JASSM, nominally considered subsonic, is actually supersonic if it incorporates the type of engine technology used to power the "super cruise" F-22 Raptor.
There may be an end run for the JASSM where the warhead detaches and then accelerates into the high supersonic to hypersonic range. Such acceleration in a vertical dive might be heavily reliant on a rocket motor. Given some artillery shells now have rocket assist the incorporation of such a feature in the JASSM's 450 kg (1000 lb) WDU-42/B penetrator warhead is quite possible.
The BrahMos can be ground, air and sea launched. Diagram indicates the varying flight profiles that can be set for BrahMos.
A third possibility is a mixed propulsion missile equivalent to the already developed Indian-Russian BrahMos. The majority of flight for such a missile may be subsonically perhaps using a turbojet, then alter its flight profile moving to a high supersonic or hypersonic end run powered by a ramjet, scramjet or rocket engine.
Higher velocity in all three missile possibilities provides a greater element of surprise, with it increased survivability as its harder to shoot down a faster missile - with reduced time for the target to deploy flares or other decoys. A faster missile also has higher kinetic energy to penetrate earth/rock/concrete (or a ship's hull) more deeply.
High kinetic energy would be particularly sought after by the US and Israel with regard to Iran's (and perhaps North Korea's) deeply dug in nuclear sites.
