Talking with Tailhooker over the weekend, he was pointing out that the F-8 Crusader had the best internal fuel capacity (9K pounds) which allowed it to work well in cyclic ops.

The F/A-18A and "C" models I hear are atrocious pigs that really don't cycle well. That was corrected with the Super Hornet.

With the US Navy having the only "Super Carriers," cycle times would have to be tight. Other fixed wing navies (Brazil, France & Argentina) have much smaller carriers with smaller compliments, so their times would be more flexible, I would guess.

VTOL carriers like the Indians, Spaniards, Italians and the Royal Navy don't have the same caveats that fixed wing ops carriers have.

Discussions?

OK, I'll go first with the stupid questions:

What do you mean by "cyclic ops"?
When you say "best" internal capacity, is that "biggest", or "best matched to the kind of operation"?

Cyclic Operations refers to the launching and recovering of aircraft in groups or "cycles". Launching and recovering aircraft aboard aircraft carriers is best accomplished non-concurrently, and cyclic operations are the norm for US aircraft carriers. Cycles are generally about one and a half hours long, although cycles as short as an hour or as long as an hour and 45 minutes are not uncommon. The shorter the cycle, the fewer aircraft can be launched/recovered; the longer the cycle, the more critical fuel is for airborne aircraft.

"Events" are typically made up of about 12-20 aircraft and are sequentially numbered throughout the 24 hour fly day. Prior to flight operations, the aircraft on the flight deck are arranged ("spotted") so that Event 1 aircraft can easily be taxied to the catapults once they have been started and inspected. Once the Event 1 aircraft are launched (which takes generally about 15 minutes), Event 2 aircraft are readied for launch about an hour later (based on the cycle time in use). The launching of all these aircraft makes room on the flight deck to then land aircraft. Once Event 2 aircraft are launched, Event 1 aircraft are recovered, fueled, re-armed, re-spotted and readied to be used for Event 3. Event 3 aircraft are launched, followed by the recovery of Event 2 aircraft (and so on throughout the fly day). After the last recovery of the day, all of the aircraft are generally stuffed up on the bow (because the landing area back aft needs to be kept clear until the last aircraft lands). They are then re-spotted about the flight deck for the next morning’s first launch.

The way I read that, someone in Event 1 can't come back in a hurry because there are aircraft in the landing area. Is that right?

Exactly.

The two S-3s on the waist cats are presumably going to be the first shots of the day, followed by the Hornets lined up facing the wrong way. None of them are coming back to the ship until the Tomcats, Hornets and Prowlers on the rear of the ship are moved up and shot into the sky.

Part I

I believe the real problem with early F-18’s was not that they were “pigs,” (quite the contrary) the real problem, they didn’t carry enough gas to do a 1.5-7 cycle without a larger tanker capability (which the navy hates to commit). So, for the longest time they navy instituted what they called “flex decking” (or something to that effect) so they could have early ready deck times for the F-18’s. Kind of threw things off.

Also, small decks are not necessary more efficient than big decks”. Actually quite the opposite. Big decks have more elevators and a really neat thing called “waist cats” so they can launch alert aircraft or tankers quickly when all the aircraft are pulled forward after recovery. That’s why in the PBS documentary “Carrier” they could continue to launch tankers for low fuel F-18, whom could not get aboard, something that was not possible with small decks whom only had two forward cats.

Miamiair is right about other country’s carriers. None carry a full complement of aircraft, perhaps 30-35. Even our old 27-Charlies (WW II with angle decks) were jam packed with 75 plus aircraft. I don’t believe any other navy fly’s at night off boats or much at all. No other carrier navy operates to the capacity or capability of the USN. Our navy fly’s all day and all night in any kind of weather in any part of the world and it can do it for a year. It also likes to fly often, which is why they run cyclic ops. Lots of training, better proficiency…more effective killers. They carry as many combat strike/offensive aircraft as they can pack on the flight and hanger decks. That’s one reason they dislike ship board tankers. One tanker equals one less aircraft to bomb somebody with. Tankers are a necessary evil and no more.
