Hell, they’re still building them.
Still the aircraft of choice for the Hurricane Hunters, I believe.
Only two WC-130s have been lost during operational missions, H-model 65-0965, on 12 October 1974, and another H-model, 65-0968, on 2 May 2018.
AWS was ordered to retain three of the Bs and could give up the other 13 in return for 11 HC-130Hs. $4.5 million was budgeted for WRAMA to transfer the Seek Cloud equipment from the Bs to the newer Hs, and the changeover occurred between June 1973 and July 1974.[6] Four additional HC-130Hs were converted in 1975.
A total of 15 HC-130H rescue Hercules were eventually modified with Seek Cloud equipment and designated WC-130H,[n 12] replacing all 16 WC-130Bs in the weather reconnaissance squadrons. The WC-130H was equipped with the more powerful Allison T56-A-15 turboprop engines rated at 4,910 horsepower and had wing-mounted fuel tanks that provided an additional 2,720 gallons (10,300 L) of fuel, extending the WC-130H's radius of action at maximum cruise speed (230 KIAS, 350 KTAS) to 2,250 nautical miles.
