HM-14 was established at NAS, Norfolk, on 12 May 1978 as the world's first fully self-contained Airborne Mine Countermeasures (AMCM) squadron.

The squadron was outfitted with eight RH-53D aircraft from HM-12 and with Vietnam War legacy minesweeping equipment from AMCM Unit Alpha, including five Mk-105 sleds.

During this period, HM-14 also responded to provide vertical onboard delivery (VOD) support following the Beirut embassy annex bombing.

In January 1987, HM-14 deployed five aircraft to Galveston, Texas conducting minehunting/minesweeping operations in support of port breakout exercise FTX Galveston '87 and another detachment deploying three aircraft to Howard Air Force Base Republic of Panama, in support of exercise Kindle Liberty '87.

As a result of superb performance in the hostile and extremely demanding environment of the Persian Gulf, HM-14 received the Navy Unit Commendation.

This detachment provided 7th Fleet with a forward-deployed AMCM and heavy-lift asset to parallel HM-15 Det Two in Manama, Bahrain.

In October 2008, HM-14 DET 1 MCAS Iwakuni, Japan relocated to Pohang, Korea continuing to provide the 7th Fleet with AMCM and heavy-lift support and performs operations in multiple countries in the Eastern Pacific.

HM-14's mission was to stand ready to deploy anywhere in the world within 72 hours via US Air Force C-5 Galaxy to provide airborne mine countermeasures and vertical onboard delivery support.

Recognizing the capabilities of the MH-53E, the squadron did also provide platforms for United States Navy EOD and Force Recon paratroopers.

The squadron had 17 MH-53E Sea Dragon aircraft and 700 total members including pilots, aircrew, maintainers, and administrative personnel.
