Over 2,500 C-130 Hercs built since 1954 hundreds still in service, somewhere around the world.
You're talking about the Spectre/Spooky/Ghostrider gunship.
Those are exclusive to USAF and yes, maybe 30 in total.
mad_as_he$$: "They mostly only come out at night and are very vulnerable when on the ground.
Plan for success not failure."
"Vulnerable" is relative to threat assessment.
Where threats are higher, vulnerability is reduced.
Also, let's ask: how many people can tell the difference between, say, Hercules and Ghostrider sitting on the ground?
Bottom line: don't even think about it, pal.
All Spectres(AC-130H) are retired. So learn how to tell them apart. Not really that hard. While at it learn how to pick out an “M” variant. All US military combat aircraft are logistics intensive operations-that is a weakness.
