Source-derived summary

The Sikorsky MH-60T Jayhawk is a multi-mission, twin-engine, medium-range helicopter built by Sikorsky Aircraft and operated by the United States Coast Guard for various missions including search and rescue, law enforcement, military readiness and marine environmental protection. It was originally designated HH-60J before being upgraded and redesignated in 2007.

Chosen to replace the HH-3F Pelican, the MH-60T is a member of the Sikorsky S-70 family of helicopters and is based on the U.S. Navy's SH-60 Seahawk helicopter, itself based on the U.S. Army's UH-60 Black Hawk helicopter. Development began in September 1986, first flight was achieved on 8 August 1989, and the first HH-60J entered USCG service in June 1990. Production ended in 1996 after 42 helicopters were produced; six retired Seahawks were also remanufactured to MH-60T specifications beginning in 2010.

In 2017, the USCG established a Service Life Extension Program to extend the service life of its current MH-60T fleet by rebuilding the aircraft with either newly manufactured hulls manufactured by Sikorsky or by conversion of retired US Navy aircraft. In 2023, the USCG obtained approval to begin acquisition of 12 additional MH-60Ts to replace some MH-65 Dolphin aircraft, the other helicopter type in the Coast Guard's inventory. In 2023, USCG received approval to transition to an all MH-60T helicopter fleet, and grew the fleet to 127 aircraft.

Development

Chosen to replace the HH-3F Pelican, the HH-60J was based on the United States Navy's SH-60 Seahawk and a member of the Sikorsky S-70 helicopter family. Compared to its predecessor the HH-3F, the HH-60J is lighter, faster, and equipped with more sophisticated electronics and more powerful engines.

For this dossier, Sikorsky, MH-60 and Jayhawk is the immediate research focus.
Editorial analysis

Why this record matters

The phrase “multi-role helicopter series by the Sikorsky Aircraft Corporation” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.

Evidence profile

The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Jul 22, 2026. The linked authority identifier is Q1892024. None of the 0 selected statements returned an explicit reference. The first chronological checks are 2007, 1986, 1989 and 1990.

Critical limits

A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.

How to read it
