As commonwealth militia units , the units in the Puerto Rico Air National Guard are not in the normal United States Air Force chain of command . They are under the jurisdiction of the Governor of Puerto Rico though the office of the Puerto Rico Adjutant General unless they are federalized by order of the President of the United States . The Puerto Rico Air National Guard is headquartered at Muñiz Air National Guard Base , Carolina , and its commander is Major General Antonio J . Vicens . Overview . Under the " Total Force " concept , Puerto Rico Air National Guard units are considered to be Air Reserve Components ( ARC ) of the United States Air Force ( USAF ) . Puerto Rico ANG units are trained and equipped by the Air Force and are operationally gained by a Major Command of the USAF if federalized . In addition , the Puerto Rico Air National Guard forces are assigned to Air Expeditionary Forces and are subject to deployment tasking orders along with their active duty and Air Force Reserve counterparts in their assigned cycle deployment window . Along with their federal reserve obligations , as commonwealth militia units the elements of the Puerto Rico ANG are subject to being activated by order of the Governor to provide protection of life and property , and preserve peace , order and public safety . Commonwealth missions include disaster relief in times of earthquakes , hurricanes , floods and forest fires , search and rescue , protection of vital public services , and support to civil defense . Components . The Puerto Rico Air National Guard consists of the following major unit : Support Unit Functions and Capabilities : History . On November 23 , 1947 , the Puerto Rico Air National Guard came into existence as a result of the efforts led by Colonel Mihiel Gilormini , Colonel Alberto A . Nido and Lieutenant Colonel José Antonio Muñiz . Gilormini was promoted to brigadier general and served as commander until his retirement in 1975 . Colonel Nido was promoted to Brigadier General and served at National Guard Headquarters as Chief of Staff for Air . Brigadier General Jose M . Portela , the youngest C - 141 Starlifter aircraft commander and captain was the only reservist ever to serve as director of mobility forces for Bosnia , served as commander of the Puerto Rico Air National Guard from January 11 , 2005 to November 2006 . The tactical aviation element of PRANG operates as the 156th Airlift Wing , 198th Airlift Squadron , flying C - 130E aircraft . They operate out of Muñiz Air National Guard Base , which shares the runways with Luiz Muñoz Marín International Airport ( SJU , originally San Juan International Airport ) . In the past , they have operated P - 47 Thunderbolts , C - 47 Skytrains , F - 86D , F - 86E , and F - 86H Sabre Jets , F - 104 Starfighters , A - 7D Corsair II , F - 16 Fighting Falcons , and , currently , C - 130 Hercules type aircraft . Phasing out the F - 16s left Puerto Rico with no air - to - air defense assets . Muñiz Air National Guard Base . Muñiz Air National Guard Base or " Base Muñiz " in Carolina , Puerto Rico was formally named in 1963 to honor of one of the initial members of the unit who was killed in the line of duty . Lieutenant Colonel José Antonio Muñiz ( full name : José Antonio Muñiz Vazquez ) was lost on July 4 , 1960 when his F - 86D lost power on climbout for a formation fly - by . Major General Orlando Llenza , then a fellow aviator in the unit , later described the loss in the following translation : We were short one pilot and Joe offered to stand in . I was formation lead . Right after departing the runway , his afterburner nozzles failed open , indicating a loss of power . The ejection seats in use at the time could not safely extract a pilot at low altitude and Joe went in little after takeoff . No one in the flight mentioned the event ; we executed the flyover and were notified of the loss upon our return to base . Shortly after that , we received the F - 86H which did not use afterburning and could fly non - stop from homestead AFB ( in Florida ) to San Juan unlike the previous D and E models , which had to stop for fuel at Guantanamo , Cuba . . Muñiz ANGB is the home of the Puerto Rico Air National Guard ' s 156th Airlift Wing and the 198th Airlift Squadron . 1981 Terrorist Attack . On 12 January 1981 , the Ejército Popular Boricua ( Boricua Popular Army ) , a Puerto Rican terrorist organization , carried out multiple bombings at the Muniz Air National Guard Base . At the time , it was the largest attack on U . S . military forces since the Vietnam War . The attack was timed to coincide with the birthday of the Puerto Rican independence advocate Eugenio María de Hostos . The attack incurred approximately $ 45 , 000 , 000 damage to ten A - 7D aircraft and a single F - 104 by eleven terrorists of the Popular Army of Puerto Rico , also known as " The Macheteros . " The unit was equipped with eighteen A - 7D and one F - 104 aircraft . Eleven saboteurs , disguised in military uniforms , penetrated the security fence and infiltrated the A - 7 parking ramp through a hole cut in the perimeter chain link fence . Investigators believe that some , if not all , arrived near the ramp in a boat surreptitiously guided along a nearby channel . The operation occurred during SP shift changeover . Security was provided by contracted , operations and maintenance funded guards . The perpetrators exited using the reverse of their entry method . Choosing to strike at shift change indicates the possibility of prior surveillance or insider information . The terrorists placed approximately 25 explosive devices on the aircraft . The explosives consisted of satchels containing four sticks of Iremite with detonators and incendiary charges . They were time delayed using a simple but effective watch and battery combination . The explosives were stolen from a Puerto Rican explosives factory , with the theft traced to this terrorist group . AFOSI ( the United States Air Force Office of Special Investigations ) called the explosives “ sophisticated ” . The entire operation took less than eight minutes and this group of semiskilled intruders was able to inflict severe damage to mission capability . Press coverage was substantial at the time of the incident but died down quickly . This was the first peacetime incident in which USAF aircraft were destroyed by a terrorist act and the first time terrorists had attacked a USAF installation on US soil . It was greatest material loss from any single act of terrorism perpetrated against the USAF anywhere in the world . The National Guard Bureau ( NGB ) was aware of the shortfalls in security at Muniz and of the threat , yet corrective actions had not been implemented at the time . The bombings resulted in increases in base security . It was revealed that there were to be 22 personnel , up from 11 , guarding the base , funded entirely by the federal government as well as electric devices added to the fence . Destroyed aircraft were A - 7D serial numbers 70 - 1050 ; 72 - 0189 ; 72 - 0219 ; 72 - 0221 ; 72 - 0222 ; 73 - 0994 ; 73 - 1005 ; 74 - 1748 , and 74 - 1755 From " GlobalSecurity . org " :
