Redlegs Stretch theirs out to 70 Clicks
Who says Tube Arty is irrelevant? The Army contends they have made the longest distance precision-guided shot in history using one.
The Extended Range Cannon Artillery (ERCA), designated the XM1299 howitzer, was developed in 2019 by BAE Systems. Based on the pre-existing M109A7 Paladin, it uses a much-longer XM907 155mm/58 caliber gun rather than the legacy 155/39, as well as a host of other improvements above the turret ring, and is planned to enter service in 2Q FY2023.
From an Army Presser:
The first successful test of a 70 km (43 miles) shot with a precision-guided munition took place on December 19, 2020 at U.S. Army Yuma Proving Ground.
The live fire demonstration used the Excalibur projectile and was the culmination of a campaign of learning on multiple systems.
“Not only did the test show the design robustness of a current fielded projectile to demonstrate lethality at extended ranges, it did so while maintaining accuracy, marking a major milestone in support of Long Range Precision Fires objectives of achieving overmatch artillery capability in 2023,” said Col. Anthony Gibbs, Project Manager for Combat Ammunition Systems.
Providing longer range than that of potential adversaries, is a significant combat multiple for maneuver commanders and the Long Range Precision Fires Cross Functional Team (LRPF-CFT) was established to tackle that objective. Their mission includes increasing lethality, improving rates of fire, and enabling deep fires to shape the battlefield and set conditions for the brigade combat team close fight.
Multiple efforts including new propellant charges, an Extended Range Cannon Artillery (ERCA) system, multiple projectiles with varying capabilities, and target identification and tracking systems, are under development to increase range and reduce the time from target identification to effects on target.
Personally, I’d like to see one or two of these guns navalised and put in low-profile mounts on the Zumwalts, perhaps alongside if not in place of the fabled Naval Rail Gun system, replacing the failed 155mm AGS. But that would make too much sense.
