en.wikipedia.org/wiki/Lockheed_C-130_Hercules

This sentence is outdated.

• The UK Parliament’s Defence Committee recorded that the RAF’s C-130J Hercules fleet was withdrawn and that 47 Squadron was officially stood down on 30 June 2023.
• The RAF’s own 2025 news coverage for the Falcons says “The RAF Falcons jump from a Royal Air Force Atlas (A400M) aircraft” during their display season.

Because the RAF no longer operates Hercules aircraft, the RAF Falcons are not currently using a C-130K for parachute drops.

The claim incorrectly assigns CC-130J to the U.S. Air Force.

• The Royal Canadian Air Force’s official aircraft page identifies CC-130J Hercules as the Canadian designation: “The CC-130J Hercules tactical airlifter…”
• Lockheed Martin, the manufacturer, identifies the C-130J-30 as “the stretch version of the C-130J airlifter.”
• Lockheed Martin also has a release specifically titled “First Lockheed Martin 'Stretched' C-130J-30 for USAF Takes Shape”, which directly shows the USAF stretch variant was referred to as C-130J-30, not CC-130J.

So the article’s sentence is backwards: CC-130J is a Canadian designation, while the USAF stretch designation is C-130J-30.

The sentence is written in the present tense, but the RAF’s C-130J fleet is no longer in service.

• A UK Parliament Defence Committee publication states that the RAF’s 14 C-130J Hercules aircraft were taken out of service by 2023 and that “47 Squadron was officially stood down at RAF Brize Norton on 30 June 2023.”
• A 2025 RAF news item about the RAF Falcons says the team now jumps from a Royal Air Force Atlas (A400M) aircraft, which is consistent with the Hercules having already been retired from RAF service.

So while Hercules C.4 and Hercules C.5 were the RAF designations for its C-130Js, saying they “are” in RAF service is no longer correct.
