Yeah, the X-7 did Mach 4.3 back in the early 60's and ASALM did Mach 5.4 in the early 80's. Yet look at all the trouble the US is having with high speed airbreathers these days. I think I could rattle off a dozen failed/cancelled efforts from just the last 20 years. Doesn't mean everybody else is going to have trouble, just pointing out that it ain't easy.
BTW, regarding Coyote as a Harpoon follow-on. If that was a requirement, Americans should have gone for MA-31 instead of Coyote. Then they'd have a supersonic ramjet target drone and a cruise missile in one.
"However, the MA-31 was only an interim solution, because the drone lacked the range and flight path accuracy to fully satisfy the Navy's SSST (Supersonic Sea-Skimming Target) requirement for the simulation of a high-speed anti-ship missile. During the MA-31 evaluation, Boeing had demonstrated an improved variant (sometimes called MA-31PG; PG = "Precision Guidance") with a GPS-based navigation system and the resulting option for a precise flight path after a high-altitude (and therefore longer range) launch, but in the end this variant was not selected for production as the ultimate SSST. Instead, that contract went to Orbital Sciences in June 2000, leading to the GQM-163 Coyote SSST. After the GQM-163 became operational, the remaining MA-31 targets were expended until the end of 2007 and the program terminated. "

Google says Coyote was a development of the failed MA-31, which is a ghetto clone we bought off of poor Ruskies of the Sizzler, missile minus electronics. (LOL kinda makes me think....we were sorta like Russia's pawn shop, you sell me your missile to become target drone to counter your missile, LMAO)
Meh....sounds easier than building a new one from scratch. Basically 1/3 of your program is already completed with that route as it already emulates the Sizzler's flight characteristics and manueverability. But yes the VLS launcher part I could see being a serious problem. Just saying...Harpoons were lookin dated back in the 80s let alone now. Of course we dont rely on anti ship missiles for control of sea lanes like other nations do.

In the 90ies France began studies to make an anti-ship missile based on the awesome ASMP (Ramjet nuke missile). Unfortunately the project was eventually dropped.
You're interpretation of what "Google says" is wrong. The MA-31 has absolutely nothing to do with Sizzler. Coyote is not base on the MA-31 but is more in common with much older Vought ALVRJ/STM

(How much Vought knowledge went into the Coyote propulsion system I do not know off the top of my head. Atlantic Research built the ramjet for Coyote. I'd be surprised if they didn't also have a hand in the Vought/USN earlier effort.)
Not to derail but an interesting ramjet paper:

Test successful :
http://www.defenseworld.net/go/defensenews.jsp?id=6827
The French Navy’s Horizon class air defence frigate, Forbin, successfully engaged a supersonic target simulating an anti-ship missile flying at very low altitude. The target was launched from the DGA’s (the Direction Générale de l’Armement) missile test centre based on the Ile du Levant in the south of France (Var region) and intercepted in flight by the Forbin’s Aster 30 system.
Another French Navy Horizon frigate, the Chevalier Paul, tracked the target and the missiles fired.
This test, carried out in conjunction with the DGA, confirmed the Navy’s ability to assure the protection of armed forces at sea (carrier and amphibious battle groups) against the most severe of anti-ship missile threats. In addition, the test marks a first for Europe with the two frigates being prepared for and then successfully carrying out a complex operational scenario, confronting a supersonic threat flying at sea-skimming altitude.
During the operation, all access to the firing zone, off the Ile du Levant coast, was forbidden by French authorities.
The Forbin and Chevalier Paul frigates, equipped with the PAAMS system (deploying Aster 30 and Aster 15 missiles) were active notably during the Agapanthe deployment in the Indian Ocean between October 2010 and February 2011 and then during Operation Harmattan. Deployed off the Libyan coast, they provided protection for naval groups linked to the Charles de Gaulle aircraft carrier as well as for the LHDs Tonnerre and Mistral. They also carried out coastal fire support operations and coordinated air activity for the coalition operating off the coast of Libya, a mission known as “Red Crown”.
