I bough some shares in this today because someday I will be shooting one of THESE!

I feel the need for speed (and want to get in on the ground floor. Think they can miniaturize one?)

Its a scam, small hypersonic projectile against bedrock. It will shatter on impact, making only superficial damage.

It really depends what's being fired, modern tank rounds will happily penetrate a meter of armored steel.

For example, a typical 1,000 foot hole will require nearly 2,500-5,000 projectiles, which may have a direct cost to our customer of approximately $5-$12 per shot. This includes the projectiles and propellant costs depending on the application and location of operations and cost of propellants.
Of course at that cost per shot they're not firing tungsten carbide but according to this claim, each projectile is penetrating a minimum of two and a half inches, which sounds reasonable to be honest.
They don't give any details of the launching system as far as I can see but I presume they're burning hydrogen and oxygen under pressure.
A similar system us detailed in this pdf report (https://www.google.com/url?sa=t&rct=j&q=&esrc=s&source=web&cd=13&ved=2ahUKEwjKmdSU0ZffAhXxYt8KHWgZCBUQFjAMegQICxAC&url=http%3A%2F%2Fwww.dtic.mil%2Fdtic%2Ftr%2Ffulltext%2Fu2%2Fa462130.pdf&usg=AOvVaw2LDsomm6vtDuRGTXAjv0X3), an investigation of the use of hydrogen/oxygen combustion gun as naval artillery by Utron Kinetics (http://www.utronkinetics.com/about_history.shtml) and the results claimed are impressive:
UTRON first developed a 15mm gun which successfully proved the concept. UTRON then designed and built a 45mm CLGG gun which successfully proved the scalability of the concept. UTRON’s 45mm CLGG gun project has fired with projectile speeds of 2.5 km/sec. An automatic loader has been developed, installed, and successfully operated. A special fuel-loading system and ignition device have also been successfully developed and deployed. Unique light-gas propellant mixture can be manufactured on the battlefield. The barrel for UTRON’s 155mm gun was designed and manufactured for UTRON by a US Army-owned arsenal. When deployed, the gun, with a muzzle energy of 64 megajoules, will be the most powerful 155mm gun in the world.

UTRON developed and built the 155mm gun that was successfully fired at UTRON’s gun range in West Virginia. UTRON’s CLGG gun has set records for muzzle energy and project velocity for a 155mm gun. The CLGG has experimentally demonstrated velocities great than 4 km/sec (13,120 ft/sec). In some tests, it has demonstrated a muzzle energy increase of 400% when compared to guns with conventional powder propellants.
