The 2nd Battalion, 20th Artillery, 1st Cavalry Division and the 4th Battalion, 77th Artillery,101st Airborne Division , along with Battery F, 79th Artillery, 1st Cavalry Division, were the only true ARA units that ever existed. [http://www.bluemax-ara-assoc.com/]Beginnings
After the helicopter proved its effectiveness in the
Korean War , the United States Army began experimenting with expanding capabilities and uses for them. In 1963, the11th Air Assault Division was activated to test the concept of air mobility. Because the 8" and 175mmhowitzer s then organic to Army divisions as general support artillery were not transportable by helicopters, ARA was developed as a substitute. When the 11th Air Assault was deactivated in 1965, then reactivated as the 1st Cavalry Division and sent to Vietnam, the 2/20th artillery, “Blue Max ” became the first ARA unit to go into combat. The 4/77th artillery joined the 101st Airborne Division in 1969 becoming the second active ARA battalion. Battery F, 79th artillery, was formed from elements of the 2/20th as units were being withdrawn from combat.Organization and equipment
Each ARA battalion consisted of one H&HB (Headquarters & Headquarters Battery) and three firing batteries. Each firing battery was equipped with 12 attack helicopters. Initially the units were supplied with Bell UH-1B and UH-1C model helicopters but these were replaced with the newer AH-1G Cobras as they became available.
The primary weapon of the ARA units was the 2.75" Folding Fin Aerial Rocket (FFAR). While the B and C model UH-1s could carry up to 48 of these rockets in two racks of 24 each (XM-3 subsystem), the faster, more powerful Cobras could carry 76. [http://www.army.mil/cmh-pg/books/Vietnam/FA54-73/ch3.htm#p51] In addition to the rockets, the UH-1s carried a single
M60 machine gun s as defensive weapons operated by the aircrafts Crew Chief, while the Cobras were armed with 7.62mm minigun s and 40mm grenade launchers. Some UH-1s were also armed with theAGM-22 wire guided missile and later versions of the Cobra with 20mmcannon .Missions
The aerial artillery batteries could and did perform any type of fire mission as performed by conventional tube artillery. These missions included support of ground troops,
landing zone (LZ) preps, interdiction, andcounter-battery fire. In addition to normal artillery missions, the helicopters were also employed as escorts formedevac and re-supply helicopters. They also were teamed with light observation helicopters to perform reconnaissance missions.Notable achievements
ARA participated in both the first and last major battles in Vietnam for US ground troops. Aerial Artillery (the 2/20th) is mentioned prominently in Hal Moore's after action report for the 1965 Ia Drang Valley operation. [http://www.combatreform.com/LTCMooreAAR.pdf] In 1970 it was the 4/77th that was heavily engaged at
FSB Ripcord near theA Shau Valley , in what was to be the last major battle involving US ground forces.At the battle of
An Loc , on April 13th, 1972, an AH-1G from Battery F, 79th Artillery became the first helicopter in history to engage and destroy an enemy tank, thus helping to secure the helicopter’s place on the modern battlefield. [http://tri.army.mil/LC/CS/csa/cptoc.htm#AnLoc]References
