There have been dozens of upgrades, -9X is the current one.  AIM-9X was designed for air-to-air use but was recently approved for use with Multi-Mission Launcher which is basically a truck with 15 launch tubes.  It could be used in Ukraine.

As I understand it, the Multi-Mission Launcher is not yet a "real" program in the US army. The adoption of Iron Dome followed by the subsequent resurrection of the MML has created a bit of a burp in the system. I don't think there are any operational ones as of now, but the Army is "committed" to this system (until it isn't). You may have better data on this than I do. Given that, we won't see the MML in Ukraine anytime soon.

Changing the topic; what is the U. S. endgame in Ukraine?

Stay the course until all fighting age Russian men are killed?  Not going to happen.

Stay the course until Putin gets frustrated and surrenders?  Not going to happen.

Stay the course until Putin runs out of money?  Not going to happen.  India, China, Pakistan and an increasing number of countries will buy Russian oil and gas.

Negotiated settlement?  Won’t be worth the paper it’s written on.  It would only be a matter of time until Putin violates the treaty.

This is a great question, and one that "undoubtedly" was thrashed out "at the highest levels" before the commitment was made to support Ukraine in an effort to "win" this war :-).  There are obviously some variants of the possible reasons Russia would leave the Ukraine. Most of these involve Putin being removed somehow and replaced with "someone more reasonable". While many of these scenarios are possible, it is unclear what, if anything, either the west or Ukraine can do to make them happen.

Hope is not a plan. Unfortunately, as long as Russia is willing to continue fighting, this war will continue. Realistically, Ukraine is not in any position to dictate terms on the steps of the Kremlin and never will be. The west needs to establish a commercial and diplomatic effort that can damage Russia enough to make them quit. This effort, coupled with significant real reverses in Ukraine is the only thing I can think of to end this mess. For certain the EU needs to get off Russian gas and petroleum by the end of 2022, worst case. The US has to ensure that the flow of technology to Russia is shut off and kept shut off. We are not doing enough in that area. Most importantly, the rest of the world has to be convinced that dealing economically with Russia is not worth the risk. Oil tankers need to be seized today before Russia has alternative delivery means, for instance. Additionally a major information campaign has to be put in place to make sure the rest of the world, including the Russian people, are fully aware of what is going on in Ukraine. Tall order, but it needs to happen.

There are serious military issues in Ukraine that eventually (if we are lucky) will need to be addressed. When the Russians are being pushed back to their own borders, more and more of the artillery fire (for example) will come from inside Russia. Right now, lots of the cruise missile launches are from inside Russian airspace. For Ukraine to expel the Russians, they are going to need to suppress lots of this fire. How do they do that without firing artillery/missiles into Russia? Today, this isn't a problem, but eventually it will be.
