US developed and tested an advanced HGV prototype Falcon HTV-2 in 2010 and 2011. This prototype was MACH 20 capable in endo-atmospheric conditions - a first in the world.
The test that was conducted in 2011 produced promising results:
An unmanned glider streaks over the Pacific Ocean at 20 times the speed of sound in a video released Thursday by a U.S. defense research agency experimenting with technology that could give the military the ability to strike any part of the globe within an hour.

This experiment was in connection to Pentagon's Prompt Global Strike program. But Pentagon scrapped HGV-2 project for unknown reasons.
Russians took inspiration from HTV-2 experiments to develop Avangard HGV. Avangard is aimed to deliver nuclear payload (strategic application).
But Pentagon is interested in broader conventional application(s).
For example:
Training with the first Long Range Hypersonic Weapon prototype system will commence on Oct. 18, says Rob Strider, deputy director of the Army Hypersonic Project Office.

US is thinking long-term in regards to application of hypersonic weapons in warfare.

You are correct to point out that NASA relied upon Russian RD-180 engines to power its rockets for a long time in a clear show of American complacency.
But Elon Musk came to the fore and slowly but surely changed the game with his SpaceX initiative.

What makes you think that Ukraine is low on troops, ammunition, and fuel?
Ukranian armed forces have significantly expanded in size during the war - from 260,000 troops at the start of war to 700,000 troops in the present.

In regards to equipment, Ukrainian armed forces have received different types of weapon systems and munitions from multiple countries around the world during the war. Ukranian armed forces have also captured a huge count of Russian weapon systems and munitions during the war.
Let us focus on Ukranian artillery forces for now. Ukraine have received over a million rounds by now and the list of suppliers have expanded in time:
Ukraine's fight against Russia has gobbled up an incredible amount of artillery rounds, with over a million provided by the U.S. alone.

Ukranian artillery forces also have qualitative edge over Russian artillery forces in the present:
In the southern Kherson region, Ukraine now has the advantage in range and precision guidance of artillery, rockets and drones, erasing what had been a critical Russian asset.

Surprise...
Ukraine have its own arrangements:
Ukraine has reached an agreement with the United States on the supply of 2 billion cubic metres of natural gas over the fourth quarter of 2022 and the first three months of 2023, Interfax news agency quoted the prime minister as saying on Wednesday.

You have fallen for older concerns and headlines. You need to
CATCH UP with latest trends.
Let us put it in this way: NATO have much better battlefield performances and achievements to show than both Russia and Iran.
Every one agree they must bomb Iran, and destroy Iran infrastructure and facilities and want Iran gone. but also every one also agree that they themselves don't do it and don't want to be part of it , but its the others that must do it. Wonder Why?
