The first two Kitty Hawks were built simultaneously within a span of 4 years. It's entirely possible that China could surprise us with a faster rate of construction than we anticipated.
I never said they couldn't be built.
I said that getting two carrier groups, and three ARGs up and running from scratch in six years is too ambitious.
There is a lot more to getting carriers and large LHAs operational and "Operating 8,000 km from home," than just completing their constructions and floating them out and breaking a bottle of champagne over them,.
The Kitty Hawk was laid down in December of 1956, launched in May of 1960, and commissioned in April of 1961.
The Constellation was laid down in September 1957, launched in October 1960, and commissioned October 1961.
Once commissioned an aircraft carrier goes through a 1-2 year work up period where it goes through more trials, gets and exercises its air wing, etc., etc. before it achieves operational status.
For example, Kitty Hawk, after commissioning in April of 1961, did not join the US 7th Fleet as an operational carrier until October of 1962. Though the Constellation was commissioned in October 1961, she was first transferred to the U.S. Pacific Fleet to her new home port of San Diego, California in July-August 1962. Then, in November, 1962 Constellation, with her air wing on board, commenced her workup exercises for her upcoming maiden deployment to the western Pacific as part of the U.S. 7th Fleet. Her first actual deployment/mission as an operational aircraft carrier took place later in 1963.
So, it took the US Navy, who at the time very already well experienced in carrier building an operations for over fifty years when the Kitty Hawk was launched, from 1956 until 1963 to get both carriers operational. Basically, seven years.
Generally, an aircraft carrier today takes even longer to build. Usually 4-5 years for constructions, one year for trials, and then commissioning and another 2 years for work up. 7-8 years.
The Chinese took eight years to refit the Liaoning and launch her. She was launched in 2011, commissioned in 2012, and now, it will soon be 2014 and she still has not got her air wing aboard yet. she is not a fully operational aircraft carrier yet...now eleven years into it.
The reality, IMHO, is that the two new PLAN carriers are bot going to be built, launched, commissioned, and worked up to an operational status in six years. Ditto on the three LHAs. I believe, even if they bust a gut, it is going to take them more like 8-9 years, and that will be a huge accomplishment. In fact, if they could build two new carriers and three LHAs and have all five operational in ten years it would be a significant accomplishment.
This is not a slam on the Chinese or the PLAN...it is just the reality of building, launching, commissioning, and working up major capital vessels like this in the modern era and in peace time.
