Introducing the Army’s Secret Weapon to Fight Russia: Super ‘Cannons’

    The big guns, with increased range, are coming soon. 

    A 70-kilometer target range is, by any estimation, a substantial leap forward for artillery; when GPS guided precision 155mm artillery rounds, such as Excalibur, burst into land combat about ten years ago – its strike range was reported at roughly 30 kilometers. A self-propelled Howitzer able to hit 70-kilometers puts the weapon on par with some of the Army’s advanced land-based rockets – such as its precision-enabled Guided Multiple Launch Rocket System which also reaches 70-kilometers.

    The Army is fast-tracking an emerging program to engineer a longer-range artillery cannon able to out range enemy ground forces by hitting targets at more than twice the distance of existing artillery.

    The service is now prototyping an Extended Range Cannon Artillery weapons with an improved tube, larger caliber round and new grooves to hang weights for gravity adjustments to the weapon – which is a modified M777A2 mobile howitzer.

    Existing 155m artillery rounds, fired with precision from mobile and self-propelled howitzer platforms, have a maximum range of about 30km; the new ERCA weapon is designed to hit ranges greater than 70km, Army developers said.

    “When you are talking about doubling the range you need a longer tube and a larger caliber. We will blend this munition with a howitzer and extend the range. We are upgrading the breach and metallurgy of the tube, changing the hydraulics to handle increased pressure and using a new ram jet projectile – kind of like a rocket,” a senior Army weapons developer told Warrior Maven in an interview.
