Navy Announces Release of the Multi-Engine Training System Draft Environmental Assessment

16 June 2023

The Navy has released a draft Environmental Assessment (EA) for the Multi-Engine Training System (METS). Implementation of the METS will replace all 54 of the T-44C Pegasus aircraft with 58 new T-54A aircraft at Naval Air Station (NAS) Corpus Christi, Texas. The new aircraft would conduct training operations in the same locations and within the same airspace as T-44C aircraft but with an increase in the number of operations.

The T-44C fleet is nearing the end of its service life and has outdated avionics, limited availability of parts, and increased maintenance cost. The replacement of aircraft would provide advanced instrumentation for communication, navigation, and tracking aircraft health to facilitate maintenance planning and efficiency. The need for the Proposed Action is to enable continued aviator training in furtherance of the Navy’s mandate to train and equip naval forces ready to deploy worldwide.

The Proposed Action would take place at NAS Corpus Christi and its associated training locations at Naval Outlying Landing Field (NOLF) Cabaniss; at international, regional, and municipal airfields; and in the Federal Aviation Administration’s National Airspace System throughout south Texas. To accommodate the new aircraft, demolition, construction, and renovation of facilities at NAS Corpus Christi would be required. These activities would include the following short-term projects:

  • Installing fire detection and suppression systems and reconfiguring the interior to maintenance shops and office space in Hangar 42
  • Reconfiguring the interior of Hangar 58 to office space and moving the maintenance equipment to Hangar 42
  • Removing the T-44C Aircraft Protective Equipment Shelters (APES), restriping, and installing T-54 APES
  • Using a portion of Building 1218 for storage of parts
  • Removing the T-44C Ground Based Training System (GBTS) and installing the METS GBTS

In the long-term, Hangars 57 and 58 would be considered for recapitalization or demolition. If demolition is selected, then either two fabric hangars would be installed or one new larger hangar would be constructed.

New T-54A aircraft would be delivered between the years of 2024 and 2026, and proposed construction would begin in 2024 and continue through 2027.

The Navy has prepared this EA in accordance with the National Environmental Policy Act (NEPA), as implemented by the Council on Environmental Quality (CEQ) regulations and Navy regulations.

This EA includes an analysis of potential environmental impacts associated with the action alternatives and the No Action Alternative. The environmental resource areas analyzed in this EA include noise, environmental justice, biological resources, cultural resources, and air quality. The region of influence for each resource analyzed is defined by how the Proposed Action interacts with or impacts the resource. For example, the region of influence for noise would include areas that may be impacted by airborne or construction noise.

The Navy has published a Notice of Availability of the Draft EA, and will be accepting public comments for 30 days (until July 17, 2023).  The draft document is available for public review online at, or in hardcopy at the following libraries:
