Normal US artillery has a range of 20-30 kilometers (12-18 miles) but new ramjet artillery will be able to reach 150 kilometers. The weapons will be able to farther, faster and higher.
150 kilometers means that if you were fighting in Belgium, then you could fire from Brussels to Bastogne. Bastogne was a famous area of fighting in World War 2. Brussels is in the center of Belgium. Ramjet artillery batteries around Brussels would be able to target almost anything in the entire country.
A shell fired at mach 2.5 enables air intakes to take in oxygen that will ignite the fuel. Removing the need for missiles and shells to carry oxidizer increases fuel capacity by five times. This can mean a mix of longer ranges and higher speeds.
Ground-based missile ranges could go from 60-70 km to go to 300-350 km (210-280 miles). air-launched missile ranges could go beyond 500 km (300 miles).
The US was converting to hypervelocity projectiles, which were just extremely aerodynamic. Hypervelocity projectiles can triple the range of artillery. The ramjet artillery would still have nearly double the range of hypervelocity projectiles.
Having primary weapons with shorter effective ranges is a huge military disadvantage.
Russia’s BM-21s have an effective range of 20-45kms. This range depends on the rockets used. Russia has always like variants of the Katyusha multiple rocket launcher.
Russia has many longer range artillery systems:
9A52-4 “Tornado” MLRS: up to 90km range
BM-30 “Smerch” MLRS: 70 to 90km range
2S7 “Pion” 203mm heavy artillery: 37,5 to 55km range
TOS-1 220mm MLRS and thermobaric weapon: 0.5 to 6km range
2S19 Msta 152.4mm howitzer: 45 to 62km range
2S35 “Koalitsiya-SV” 152.4 or 155mm artillery: 40 to 80km range.
The US has had longer-range multi-rocket systems but they are far more expensive than the Russian versions.
Israel Rafael Bolt On Guidance for Missile Artillery
In 2018, Rafael (Israeli weapon maker) was working on an add-on upgrade package, known as the Electro-Optical Precision Integration Kit, or EPIK. It could turn any Soviet-standard 122mm Grad artillery rocket into a precision-guided round capable of hitting stationary or moving targets.
Artillery Costs and HVP Costs
Anti-cruise missile weapons currently cost $1 to $2 million while hypervelocity shells are 25,000 to $100,000 range. The HVP that cost $75,000 to 100,000 are the fanciest version with an onboard seeker. Regular Artillery shells cost about $600-7000. The cost variance depends upon adding in more explosive or chemicals.
