The Navy’s Recent Howitzer Apt Hit a Goal 43 Miles Away. On the Nose.


    The U.S. Navy has dramatically increased the vary of its howitzer weapons, environment a new distance document.

    You esteem badass militia tech. So enact we. Let’s nerd out over it together.

    In a new test, the Prolonged Vary Cannon Artillery (ERCA) gun fired a precision-guided shell to a vary of 43 miles, or ample to shell Washington D.C. from Baltimore. The Navy says the gun now holds the sphere document for precision strikes … nonetheless a new Russian howitzer would perchance well presumably moreover soon disaster that.

    The Navy conducted the test, in accordance with Protection Recordsdata, at Yuma Proving Floor in Arizona, firing an M109A7 Paladin Integrated Administration (PIM) howitzer fitted with a long, 58-caliber gun. (In self-discipline artillery, “caliber” refers to the length of the gun barrel and never the diameter of the bore. The 155-millimeter diameter of the barrel is multiplied by 58 to settle the total length of the barrel, or 29.49 toes.) A longer barrel enables increasing gases attributable to the shell powder to behave upon the projectile for the next length of time, increasing velocity.

    The other half of ERCA is a new “supercharged” propellant system designed to form bigger stress interior the barrel.

    The 2 new technologies combined to enable the Navy to fireplace a GPS-guided “Excalibur” artillery round to a total of 43 miles. The ERCA test fervent firing three rounds; one missed attributable to excessive winds, and the 2nd missed attributable to a hardware failure. The third, nonetheless, hit the target.

    ERCA almost doubles the vary of existing Navy howitzers. In step with the Navy, the present M109A7 Paladin self-propelled howitzer can ship Excalibur rounds to 39.3 kilometers (24.4 miles), which ERCA can now lob to 43 miles.

    Excalibur is a Raytheon-developed shell with jam-resistant GPS, guidance fins, and a unitary excessive explosive warhead. First fielded within the early 2010s, new versions of Excalibur can strike a target within 2 meters.

    ERCA would perchance well presumably moreover already absorb a challenger: the Russian 2S35 “Koalitsiya” (“Coalition”) 152-millimeter self-propelled howitzer. Much just like the M109A7, the 2S35 is reported to absorb a vary between 40 and 80 kilometers.

    The excessive discontinue of that estimate would form it a long vary weapon than ERCA, though it’s now not clear if that adjust involves the use of precision-guided shells.

    In March 2020, the Russian newspaper Izvestia reported the nation used to be increasing a new rocket artillery shell that would perchance well presumably give the 2S35 and the older 2S19 howitzer a vary higher than 100 kilometers.
