SH-60F to MH-60T Conversion Process

SH-60F to MH-60T Conversion Process, ALC

With the loss of HH-60J airframe CG-6020 in 2004 during the daring Alaskan rescue of the crew of the Malaysian freighter, Selandang Ayu, CWO Montgomery Everson (ret) of the Medium Range Recovery (MRR) Projects Cell at the Aviation Logistics Center (ALC), looked for innovative ways to fill the Service's critical need aircraft gap. Collaborating with CG-41 and CG-71, “Monty” Everson completed a thorough engineering analysis and determined that the Navy's SH-60F Seahawk could be viably converted into the Coast Guard’s unique MH-60T configuration for $12M less that than procuring a brand new helicopter through the original equipment manufacturer (OEM).

Sikorsky's production line had stopped producing these aircraft in the early 1990's so the Aviation Logistics Center turned to the Navy as they were experiencing their own fleet recapitalization, including retirement of the SH-60F helicopter. Everson realized the Coast Guard had the necessary industrial fixtures, processes and technical experience to convert the SH-60F into the Coast Guard's MH-60T. Working closely with the OEM, Sikorsky, and Naval Air Systems Command (NAVAIR) but with no proven roadmap, Everson developed a comprehensive procedure to modify significant portions of the 60F, including the cabin subfloor, left hand bulkhead and nose area to meet the Coast Guard's MH-60T's engineered specifications. No other military service or Sikorsky had ever undertaken such a vast technical task.

The first replacement aircraft, CG-6043, affectionately called Franken Hawk, began flying operationally in September 2009. When visiting Elizabeth City, one cannot pick out which of the 60's is not an original Coast Guard helicopter; it is seamless to the fleet.

The closest available aircraft version - the MH-60R - would cost the Coast Guard approximately $45 million to acquire. Not only expensive, there would be no standardization across the rotor wing fleet. Everson's process yielded a replacement aircraft including the avionics upgrade package for the Coast Guard fleet under budget for approximately $18 million.

Not a one-time deal, the Coast Guard has acquired two additional Navy SH-60F hulls with extremely low flight hours. The Coast Guard has already converted the second hull and is currently in the PDM process and will become the CG-6044. The third hull arrived at Aviation Logistics Center mid October where it is currently being disassembled for conversion.

In addition to the huge cost savings is the savings in delivery time. This new process of converting retired Navy helicopters reduces the delivery time for future aircraft by approximately 18 months.
