Editing Malmstrom Air Force Base (section)

===Post-Cold War era===
The 40th Air Division was activated at Malmstrom on 7 July 1989. A third of the base's personnel (about 1,800 people) were assigned to it, including support personnel from the 341st Strategic Missile Wing. Historian, judge advocate, public affairs, and safety were now designated 40th Air Division, while combat support, resource management, security police, and strategic clinic were redesignated 840th.<ref>{{cite news|title=Base Unit Designations to Change|work=Great Falls Tribune|date=22 May 1989|page=7}}</ref>

On 1 September 1991, the 341 SMW became the 341st Missile Wing. Also in 1991, the [[START I|Strategic Arms Reduction Treaty]] (START I), was officially formalized. President Bush took all Minuteman II missiles, bombers and tankers off alert status on 27 September. In November 1991, the 12th Missile Squadron's Launch Facility J-03 became the first to have its missile removed in compliance with the order. It would be three and one half years, until the last Minuteman II in the Air Force inventory was removed from Kilo-11 on 10 August 1995. As Minuteman II missiles were removed, a new program called Rivet Add was launched, modifying the 150 Minuteman II launch facilities to accommodate the newer [[LGM-30 Minuteman#Minuteman-III .28LGM-30G.29: the current model|Minuteman III]], transferred from [[Grand Forks Air Force Base|Grand Forks AFB]] in northeastern [[North Dakota]].

With the inactivation of SAC on 1 June 1992, Malmstrom temporarily became an [[Air Mobility Command]] (AMC) base with the 341st Missile Wing as an [[Air Combat Command]] (ACC) tenant unit.

The 301 ARW was subsequently inactivated and replaced by the [[43d Air Refueling Wing]] (43 ARW) as a KC-135R unit reporting to [[Fifteenth Air Force]] (15 AF), then located at [[March Air Force Base|March AFB]], [[California]]. The 341 SMW was redesignated as the 341st Missile Wing (341 MW), reporting to ACC's [[Twentieth Air Force]] (20 AF) located at [[F.E. Warren Air Force Base]] at [[Cheyenne, Wyoming]]. Following an Air Force decision to divest ACC of all ICBM units and assets, the 341 MW was subsequently transferred to [[Air Force Space Command]] located at [[Peterson Air Force Base]] at [[Colorado Springs, Colorado]]. This mid-1993 move merged all missile and space operations under one command. In October 1997, the 341 MW, along with all other missile wings, was redesignated as the 341st Space Wing (341 SW).

In 1994, the 43 ARW was downgraded in status and redesignated as the 43d Air Refueling Group (43 ARG). In 1996, the 43 ARG and its [[KC-135R]] aircraft were transferred from Malmstrom to [[MacDill Air Force Base|MacDill AFB]] at [[Tampa, Florida|Tampa]], Florida, as part of a [[Base Realignment and Closure]] (BRAC) action, merging with MacDill's 6th Air Base Wing to form the current [[6th Air Refueling Wing]]. With the loss of its only fixed-wing flying unit, Malmstrom's runway was decommissioned as a cost-savings measure following departure of the last [[Boeing KC-135 Stratotanker|KC-135R]] aircraft in 1997. Malmstrom's air traffic control tower was leveled, the navigational aids were turned off and runway was closed and currently remains inactive. One hangar and a portion of the Malmstrom flight line remain operational for aviation purposes as heliport for Malmstrom's 40th Helicopter Squadron (40 HS) and its [[Bell UH-1N Twin Huey|UH-1N Twin Huey]] helicopters supporting the 341st Space Wing's Minuteman III ICBM sites.

On 18 May 2007 there was an incident involving the visiting [[Canadian Forces]] aerial demonstration squadron, the "[[Snowbirds (aerobatic team)|Snowbirds]]". While practicing, a lap belt failed in one of the Snowbirds' aircraft, resulting in a mishap that killed the pilot of Snowbird 2.

Malmstrom had been used for the site of an experimental coal to synthetic fuel plant for potential use in USAF aircraft in 2008.<ref>{{Cite web |date=2008-03-31 |title=Air Force wants coal for fuel, but will idea fly? |url=https://www.nbcnews.com/id/wbna23811258 |access-date=2023-08-08 |website=NBC News |language=en}}</ref>

On 6 May 2008, ''[[NBC Today Show]]'' personality [[Al Roker]] broadcast live from Malmstrom AFB as part of an "Access Granted" series centered on places the American public doesn't get to see firsthand. Roker and his crew were permitted access to a [[missile silo]] and he interviewed various squadron members about the policies and procedures should a nuclear response ever be directed by the [[President of the United States]].

On 1 July 2008, the 341st Space Wing was redesignated as the 341st Missile Wing.

Two launch facilities at the base showed [[Polychlorinated biphenyl|PCB]] levels higher than the thresholds recommended by the [[Environmental Protection Agency]] when extensive sampling began of active U.S. intercontinental ballistic missile bases to address specific cancer concerns in 2023.<ref>{{Cite news |last=Copp |first=Tara |date=2023-08-07 |title=Carcinogens found at Montana nuclear missile sites as reports of hundreds of cancers surface |url=https://apnews.com/article/missile-bases-cancer-air-force-malmstrom-military-1999fad70393f0d141676b7faa587eda |access-date=2023-08-08 |work=AP News |language=en}}</ref>
