Otis Air National Guard Base (IATA:FMH,ICAO:KFMH,FAALID:FMH) is anAir National Guard installation located withinJoint Base Cape Cod, a military training facility located on the western portion ofCape Cod inBarnstable County, Massachusetts,United States. It was known asOtis Air Force Base prior to its transfer from the active duty Air Force to the Air National Guard. In the local community, it is more commonly known asOtis Air Base or simplyOtis. It was named in honor of pilot and Boston surgeon Lt.Frank "Jesse" Otis.

Today major units include theCoast Guard Air Station Cape Cod,Coast Guard Base Cape Cod and the102nd Intelligence Wing. Other units include the wing's101st Air Operations Squadron, the253d Cyberspace Engineering Installation Group, the 212th Engineering Installation Squadron, the267th Combat Communications Squadron, the202nd Weather Flight, the 3rd Battalion,126th Aviation Regiment, part of the29th Infantry Division (Army National Guard), and the Coastal Patrol Squadron 18, Cape Cod Composite Squadron 044-Massachusetts Wing (Civil Air Patrol).

Otis Air National Guard Base is named for pilot,flight surgeon, and eminentBoston City Hospital surgeon Lt. Frank "Jesse" Otis.^[2] He was a member of the101st Observation Squadron who was killed on 11 January 1937 when hisDouglas O-46A crashed atHennepin, Illinois while on a cross-country training mission. In 1938, the landing field area atCamp Edwards was namedOtis Field in his memory. Ten years later, the base was renamed Otis Air Force Base in his honor. During theKorean War, it was used by the Army to providebasic training. Until 1973, it was the largestAerospace Defense Command base in the world. DuringWorld War II, the field was known asNaval Auxiliary Air Facility Otis and was a subordinate field forNaval Air Station Quonset Point,Rhode Island.

During theCold War, the base was a keyAerospace Defense Command (ADC) installation. Activities included the33rd Fighter Wing, the4604th Support Squadron supporting theTexas Towers (1956–63), the60th Fighter-Interceptor Squadron, and the551st Airborne Early Warning and Control Wing aircraft, flying over the Atlantic Ocean from 1954. The 551st flew theEC-121 Warning Star before moving toHanscom Air Force Base in 1969. The 551st was also the first Air Force wing to fly the EC-121. The 33rd flew various fighter jets in conjunction with the 60th Fighter Interceptor Squadron. The expanding mission led to the runways being lengthened in 1960. The base was also home to the26th Air Defense Missile Squadron, which operatedBOMARC surface-to-air missiles. The regular air force began leaving Otis in the late 1960s as improvements in radar made the 551st more costly when compared to newer technologies. The 551st and the 60th left Otis when the Air Force began to move the continental air defense mission over to theAir National Guard.

Strategic Air Command maintained the19th Air Refueling Squadron at Otis AFB flying theKC-97 Stratofreighter. After the squadron inactivated, SAC assigned Detachment 1,416th Bombardment Wing/41st Air Refueling Squadron, based atGriffiss AFB,New York with 2KC-135 Stratotanker and 299th Bombardment Wing /99th Air Refueling Squadron,Westover AFB,MassachusettsKC-135 Stratotankers on 24 Hour Alert Duty.

After active duty units left, theMassachusetts Air National Guard's102d Fighter Wing (102 FW) became the main unit at the base, flying fighter and air defense missions. During the Cold War period from 1964 until 2004, the 102 FW operated a variety of air defense and tactical fighter aircraft, including theF-86H Sabre,F-84B/F Thunderstreak,F-100D Super Sabre,F-106A/B Delta Dart andF-15A/B Eagle. The Wing's101st Tactical Fighter Squadron shared missions with the33rd Tactical Fighter Wing during the Cold War. In 1987, the 102 FW transitioned to theF-15A Eagle, and, later, to the F-15C Eagle.

The base was also utilized as a stopover for aFrench Air ForceMirage IV on the way toFrench Polynesia forOperation Tamoure.

Following the2005 Base Realignment and Closure Commission, the 102 FW was directed to transfer its F-15 aircraft to its sister unit, the104th Fighter Wing atBarnes Municipal Airport/ANGB. All F-15 aircraft were transferred by January 2008 and the 102 FW was redesignated as the102d Intelligence Wing (102 IW), a non-flying unit.

PresidentJohn F. Kennedy used Otis on many occasions for the landing of Air Force One when he traveled to theKennedy Compound inHyannis. He would then board an Army or Marine Corps helicopter which would then take him to the compound. It was at the Otis AFB Hospital that his wife, Jacqueline, gave birth to their sonPatrick Bouvier Kennedy, who died two days later.

In the early 1970s, Otis AFB was marked for closure as part of a nationwide reduction of military bases, to cut costs as the Vietnam War wound down. In 1973,Governor of MassachusettsFrancis W. Sargent appointed the Otis Task Force to oversee a phase-down of military activities at the Massachusetts Military Reservation (MMR). The major concern of Cape residents was the fate of base property and impacts on the local economy as military activities decreased. While the future of the base was in limbo, ideas were floated that would include the redeveloping of the base into a recreation center of sorts that would rivalDisneyland.^[3] The state even went so far as to mail out brochures to 1,500 corporations around the world, advertising the redevelopment opportunities of the base.^[3]

In 1977, Otis AFB was officially redistributed with the establishment of boundary lines which divided the complex into several installations, all within the confines of the original Otis AFB. Established was Otis Air National Guard Base,Camp Edwards (an Army National Guard small arms training facility that served as a POW camp during World War II), andCoast Guard Air Station Cape Cod (which utilizes the Otis ANGB runways). Together they form theMassachusetts Military Reservation, where 17 other state, federal and private entities operate within its boundaries.

In 1978, the Regular Air Force returned to Otis ANGB with the construction of thePrecision Acquisition Vehicle Entry Phased Array Warning System (PAVE PAWS) near theCape Cod Canal. PAVE PAWS is designed to detect airborne ballistic missiles and monitor orbiting satellites.

PAVE PAWS is an Active Space Force site and consists of the 6th Space Warning Squadron. This unit is known as Cape Cod Air Station and not directly affiliated to Otis ANG, Base.

Otis ANGB was originally scheduled to be closed by the 2005Base Realignment and Closure (BRAC), but it was spared in last minute decisions. However, the 102nd Fighter Wing did lose itsF-15 Eagle and transitioned to a non-flying mission, redesignated as the102d Intelligence Wing. The only military aircraft currently based at Otis ANGB are those of the Coast Guard and Army, although transient military aircraft continue to use the facility, and the Navy has considered it as a place of interest should they decide to base naval forces in the Northeast again.^[4][5]

A partnership was created on December 22, 2006 among the Coast Guard, National Guard, and the Commonwealth of Massachusetts. The Coast Guard assumed control of the aviation facilities from the Air Force, the Air National Guard took over the management of the utilities, and the state funds the emergency services and fire protection. Improvements to the lighting system were put in control of the Coast Guard.^[6] TheFederal Aviation Administration has released new flight procedures that identify theICAO code KFMH with the name ofCoast Guard Air Station Cape Cod.^[7]

On November 6, 2009, ground was broken on new facilities for the102nd Intelligence Wing.^[8] The airport was aNASASpace Shuttle launch abort site.^[9] In May 2013, it was announced that one third of the104th Fighter Wing's F-15 aircraft would be moving to Otis to take up an alert mission for four to six months, asBarnes Municipal Airport's runway underwent renovation.^[10][11]

In December 2013, Otis was selected as a test site by the United States Federal Aviation Administration to "aid in researching the complexities of integrating Unmanned Aircraft Systems into the congested, northeast airspace."Massachusetts Institute of Technology will work with Otis to test drones at the airport.^[12]

OnSeptember 11, 2001, theNorth American Aerospace Defense Command alerted the base at 8:41 to be put on battle stations. Four minutes later, Lieutenant Colonel Timothy Duffy and Major Daniel Nash were scrambled and flewF-15 Eagle fighters out of the base heading toward New York City to interceptAmerican Airlines Flight 11.^[13] They departed somewhere between 8:46 and 8:52.^[14][15] Both pilots were interviewed in the 2006 documentaryFlight 175: As the World Watched.

Military operations in the early years at Otis AFB included the use of petroleum products and other hazardous materials, such as fuels, motor oils, and cleaning solvents, and the generation of associated wastes. It was common practice for many years to dispose of such wastes in landfills, dry wells, sumps, and the sewage treatment plant. Spills and leaks also occurred. These activities had a serious impact on the Upper Cape's groundwater resources; much of the water supply in the surrounding area was converted from wells to municipal water sources as a direct result of the threats from wasteplumes in the groundwater.

Residents of nearby towns raised concerns about possible adverse effects on health of humans resulting fromPAVE PAWS radiation. Remediation on the site occurred in 1998^[16] and a 2005 report from the National Academies Press found no evidence of adverse health effects fromPAVE PAWS.^[17] In 2012, a wind turbine started operating in the area which is powering 25-30% of the energy used in the remediation effort.^[18]

• 14 February 1951: MajorRaymond S.
