About this opportunity
The United States Coast Guard is seeking information regarding an Environmental Control System (ECS) to replace the vapor cycle refrigeration system currently installed in the MH-65 helicopter through a Request for Information (RFI) issued pursuant to Federal Acquisition Regulation 15.201(e). The procurement seeks a replacement system that is lighter in weight and has greater cooling capacity than the existing system, utilizing any available cooling technology including vapor cycle, bleed air, and electrically or mechanically driven systems. Respondents must address specific questions regarding business classification (small business status, disadvantaged business certification, HUBZone certification, woman-owned or Service-Disabled Veteran-Owned status), GSA schedule listing, and references to other government agencies using the product, along with submission of company capability statements. This RFI is strictly for market research and planning purposes only; no contract will be awarded from this announcement, and all submissions become the property of the federal government. The deadline for responding to this RFI was December 19, 2025, with two vendor questions and answers already provided addressing contractor engineer on-site requirements and clarification that the Coast Guard seeks currently available systems with minor modifications rather than custom-designed first-of-a-kind systems.
This RFI contains no set-aside designations and identifies no incumbent contractors. The performance objectives specify that the replacement ECS must deliver 3 or more tons of cooling capacity with 600 CFM total airflow, direct 100 CFM of cooled air to the avionics compartment at 38 degrees Fahrenheit minimum, and maintain a maximum weight of 100 pounds (with 35 pounds as the desired target). The system must operate in external temperatures up to 103 degrees Fahrenheit while maintaining cabin temperature at 73 degrees Fahrenheit and must be capable of cooling avionics up to the H-65 maximum operating temperature of 122 degrees Fahrenheit. No specific award value or budget range is disclosed in the RFI documentation. The preferred equipment dimensions are 11.5 inches by 28 inches by 28 inches, and the system must include water separation, temperature protection between 38 and 170 degrees Fahrenheit, and separate temperature sensors and controls for avionics and cabin areas.

Additional Project Details and Objectives
1.0 Scope
The environmental control system for cooling may be installed in all MH-65 aircraft. The requirement will include spare parts and support. The system and associated support plans will be designed to minimize government inventory requirements.
2.0 Background
The MH-65 is a derivative of the Airbus Helicopters Dauphin aircraft. The current configuration is similar to the AS 365N3. The aircraft is powered by two Turbomeca Arriel 2C2− CG engines.
The aircraft was originally built to Federal Aviation Regulations Part 29 standards. Modifications to the aircraft are designed to current Federal Aviation Regulations Part 29 standards with exceptions approved for Coast Guard specific requirements.
The original avionics system of the MH-65 aircraft has been upgraded to a Common Avionics Architecture System (CAAS) to provide substantial additional communication and sensor capabilities. The newer avionics components are capable of operating with less conditioned air than that required for the original MH-65 avionics system. However, there is a now a greater need for cooling air in the cabin.
The MH-65 was originally equipped with a bleed air ECS. The bleed air cooling system was removed early in the development of the MH-65 in order to preserve the engines. The bleed air heat function was retained. A vapor cycle (Freon) system was installed to eliminate the need for the engines to provide bleed air for cooling. The current heat exchanger has been modified further to operate on FR-12 refrigerant.
The Coast Guard is looking to the open market for solutions that can replace the current system while gaining weight savings and increased cooling capacity to meet present and future avionics upgrades.
3.0 Support
A Performance Based Logistics (PBL) support strategy is desired. The support structure will be based on existing Coast Guard support contracts. The support strategy will be included in the system procurement process.
3.1 Open Architecture
The aircraft will be designed to incorporate open architecture to the greatest extent possible and use standard government and commercial protocols. The system should minimize proprietary interfaces and systems. Data developed at government expense will be used by the government without restriction.
A full documentation package is desired. The minimum documentation requirement will include a detailed interface control documentation and system data necessary for troubleshooting and maintenance.
Universal connections are required for any interface to refrigerant servicing carts if proposed systems are maintained with their use.
3.2 Integration
Vendors submitting capability information must include information on their ability to supply an Engineer on-site throughout the development and integration phase. The Contractor Engineer would interface daily with ALC on-site engineers and will also be required to perform tasks inside the helicopter through all operational ground and flight-testing phases.
4. Vendor Qualification
The supplier must be an original equipment manufacturer for aircraft environmental control systems. The supplier must be FAA certified and must have been awarded a Supplemental Type Certificate (STC) for environmental control systems installed on other aircraft. The Coast Guard will use this STC information as a basis to gauge quality in regards to the product and customer support.
The supplier must have experience working with civil and/or military airworthiness authorities. The supplier must explain in their response how they would support the airworthiness certification of the installation.
The supplier must have or establish a permanent presence in the United States staffed with English speaking technical support personnel. All system documentation must be available in readily understandable English language format.
5. Evaluation
After evaluation of the information received, the Coast Guard may issue a separate request for proposals.
It is critical that, prior to submitting a response to this RFI, the vendor will be responsible for the review all attached enclosures. The compartments that house the current ECS cannot be modified. Therefore, submissions that will not fit into the designated spaces will not be considered for Request for Proposal (RFP) development or as potential candidates for award. Any follow-on RFP will include this statement as well.
If more than one qualified vendor is identified, the request for proposals will include an evaluation and source selection process. This process will be designed to consider each offeror's capability to provide a technical solution that best aligns with the project objectives, is within the proposed schedule, and is affordably priced. An integrated assessment of the strengths, weaknesses, and risks of each offeror's proposal, together with the cost proposed, will be used to determine which proposal offers the best overall value to the Government.
