Oh well, it is all CG after all, and apparently created by an individual, alok ranjan, and placed on youtube.
the video was released by directorate of naval shipyards,but out of curiosity can the f 15 be modified to take off from ski jumps, if the heavier su33 can do it then shouldnt it be able to do it too

SU-33, J-15, Mig-29K were all specifically built to be naval aircraft.

The F-15 was not. It would have to be strengthened structurally, a new undercarriage/landing gear designed, tail hook added, and then protected against the sea environment.

There is really no expectation or plan whatsoever for the F-15 to be navalized.

IMHO, putting an aircraft that resembles an F-15 on the carrier hurts the credibility of the overall video. For the Indian carrier they should stick with the Mig-29K, the Rafael M, and the navalized Tejas...with still an outside chance at the F-35C perhaps.

So true Jeff..

Long a ago when I was stationed at NAS Miramar Top Gun's hangar was very close to the parachute loft where I worked. I think it was in 1986 USAF F-15s were being hosted by Top Gun. We went out out on the flight line to check those Egales out and started making jokes about how weak their landing gear was as compared to a Tomcat or a Phantom. The zoomies, i.e USAF airmen, did not like our comments and fisticuffs almost ensued but cooler head did prevail along with a couple brewskies at the EM club later that afternoon.

Hehehe...wow as I read that, in my mind's eye, I could see it happening.

USN & USAF on the USAF flight line said:
Air Force Chief: "What are you sea legs doing around here?"

Navy Chief: "We came over to take a look at your "hot" birds."

Air Force Chief: "Well, what do you think?"

Navy Chief: "What do I think? Well, I think that I have never seen such a bunch of weak, spindly legged aircraft in all my life. I like my birds with a lot more meat on the bone. That's what I think!"

...and it probably went down hill from there, until later at the EM Club. LOL!

I know that magazine is dated Feb 2014 but that news was published last May.

When USAF chose to have the Phantom adapted to its use the designers will have saved a lot of weight on the undercarriage and generally in the structure of the aircraft while of course increasing the size of the wheels.

Well, the US Navy and US Air Force have had three fighter/attack aircraft that were jointly used to date. They were:

- The FJ-2/3 Fury was a F-86 Sabre design redone for US Navy aircraft carrier use. US Navy use 1954-1962
- The F-4 Phantom II was a US Navy aircraft redone for US Air Force use. US Navy use 1960-1986
- The A-7 Corsair II was a US Navy aircraft redone for US Air Force use. US Navy use 1967-1993.

Now, with the F-35 we see an aircraft that from the outset has been designed to be used in three different variants by all three services, including the STOVL role for the US Marines.

I understood that the Sabre was really a new design but based on the Fury the team had developed just before but that Phantom II and Corsair II were really adaptation. Adaptations in the other direction, from Air Force to Navy, didn't happen in the US in the jet era?
Common development was tried once before, the notorious TFX, that provided the Air Force with the F-111, but is I think the wrong way to go about designing an aircraft.

It seems to me that Su-33 compared with Su-27 is in between adaptation and new design. J-15 is based on J-11B but is a next generation Flanker, together with J-16. Perhaps we can consider J-15 and J-16 as common development?

Well, the F-84 Sabre was purely a US Air Force design, and it came first, before the FJ-2 Fury. At the time, the US Navy was waiting for the F-7U Cutlass and the F-9F Cougar, but they were some time away from being ready for production, so as an interim measure the Navy decided to create a US Navy version of the F-84 and it was ultimately designated the FJ-2 Fury. Upgrades to that design were called the FJ-3 Fury.

The F-4 Phantom II was a US Navy design that entered service for the US Navy in 1960. The US Air Force liked what they saw and they adopted it, not requiring as heavy a landing carriage or arrestor hook. In USAF service the F-4 was initially called the F-110 Spectre. But in 1962, the US Military adoped the United States Tri-Service aircraft designation system, which changed the designation back to the F-4. The USAF F-4 design ultimately became the largest user of the Phantom II, with the F-4C, D, and E versions for Air Force use. The first full production aircraft entered service in 1964 for the US Air Force.

An interesting note about the F-4 Phantom II is that the US and Germany ultimately sent a total of 192 aircraft to Turkey who still operates many of them today, in 2014. One of the Turkish Recon F-4 Phantom IIs was the aircraft that was shot dwon in the Syrian conflict last year.

The A-7 Corsair II was a US Navy attack aircraft design with very good manueverability dog-fighting capabilites, and able to carry a lot of weight and loiter for long periods over the battle field. It was introduced into US Navy service in early 1967. It was another design that the US Air Force liked and adopted, the US Air Force version, the A-7D entered US Air Force service in 1970.

The US Air Force A-7D differed from the Navy's Corsair II in several ways. The Air Force wanted significantly more power for A-7D and selected the Allison TF41-A-1 turbofan engine, which was a license-built version of the Rolls-Royce Spey. It offered a thrust of 14,500 pounds, which was over 2000 pounds more than the TF30 engine that the Navy's Corsair IIs used. Other changes included a heads-up display, a new avionics package, a M61 rotary cannon in place of the two single-barreled 20-mm cannon, and a computerized navigation/weapons delivery system with AN/APQ-126 radar. In turn, the Navy liked and adopted the US Air Force improvements and the follow-on US Navy aircraft orders, which also had the strenghtened undercarriage, the arrestor hook, and the refueling probe, became the A-7E aircraft that were the main stay A-7 Corsaitrs for the US Navy.
