Cannon Spectres Pass the Torch
The venerable AC-130H gunship bowed-out with an eight ship formation flight marking its last mission with the 16th Special Operations Squadron at Cannon AFB, N. M., this month. "Being able to get all eight of the AC-130H aircraft up is remarkably unique and required everyone to play a vital role," said 16th SOS Commander Lt. Col. James Mott, after the Jan. 16 flight. The unit is retiring the legacy AC-130H as part of Air Force Special Operations Command's transition to the new AC-130J, which is due to begin operational service in 2015. "As we close the books of the C-130H aircraft, we remember how phenomenal this plane was for more than 40 years," Mott said. "Now we transition onto newer models of the C-130 and begin to write new chapters of Air Force history." (Cannon report by SrA Xavier Lockley)
One assumes it's just Cannon that's ceasing operations with the AC-130H and other AFSOC units will continue to fly the current Spectre platform until the AC-130J comes on-line next year.
There are seven high-res photos of the Spectre and the final mission ceremony at the "Cannon report" link, you should go look. Those pics include one that would have had EVERY first sergeant I ever had during my career tearing their hair... assuming they had hair; some did not... out. Why? Because there are at least four people with their hands in their pockets in the group photo of the 16th SOS. "Not your father's Air Force," indeed.
