The problem is that, if the US Navy went ahead with the project, then it will be equiped in the US Navy. Does anybody know why the US Navy cancelled the project?

Look at the dates on these. The most modern is in the 80's. Back then there was no high speed computers. To launch a supersonic missile without a guidance system that can correct in real time is a waste. We don't have that problem anymore, 25 years later. The AMRAAM is a mach 4 missile, and it uses almost the latest CPU technology and is deadly against an aircraft flying at mach 2+. So if we put the same guidance system on a mach 2 ASM, we win. YC my friend, I worry that you worry too much.

This is how Erectile Power III Supersonic Anti-Shipping Missile looks like. Sorry for the crude, primative way of putting propulsion rockets.
Warning, large pic.

Could this be what you are looking for?  Mach 3 plus - air and surface launch...

Didn't know that Fasthawk has a follow-up project. This is a crazy idea to use turbine jet to reach Mach 3 and fly over 250km.

Well, RATTLRS is only at the concept stage, and I agree it's about time we get hysterical about not having supersonic cruise missiles as the other side does.

Not your daddy's turbine jet either, Yelli...

Here is some data from Av Week and Lockheed -
Lockheed Martin Readies New Missile Concept
Aviation Week & Space Technology
05/28/2007, page 46

Key to Rattlrs is the Rolls-Royce Liberty Works turbine-based combined cycle YJ102R engine. The engine, which can be throttled, exploits the XTL-15/17 development work carried out on behalf of both the U.S. Navy and Air Force in the 1990s.
The AADC YJ102R engine provides the supersonic cruise capability of the legendary SR-71 spy plane in a simple and inexpensive engine suitable for an expendable missile.
U.S. advances in turbine cooling technology allow the YJ102R to provide more than six times the power of the SR-71 engines, allowing the RATTLRS vehicle to cruise at high speed without the high fuel consumption of conventional jet engines.

What will probably happen is an anti-ship missile that can be launched from all platforms, self-guiding with target updates, subsonic to supersonic speed, re-attack capable, stealthy, datalinked, and can be adapted for land attack if necessary. Basically, a Harpoon on steroids with high ASVAB scores.
