Slightly off topic here. Can F-35B take off vertically and make the transition from vertical flight to horizontal flight in the air? I have seen videos of Harrier doing that, but I have yet to see any video on F-35B performing such flight transition.

Of course it can. The USMC would not replace the Harrier with this aircraft if it could not. If it can come in for a landing then go vertical.. it can certainly do the same during a take off.

Honestly , I could not find a video on this subject.

I trawled around the internet but no one seems to be able to give a straight answer on this. What I found was that vertical-to-horizontal take off is not a JSF program requirement, so no surprise if it can't do that. Then again I guess such capability has very little practical use beyond showing off during air show, but the sight of a a fixed wing aircraft taking off vertically, hover around and then fly off into the sky has got to be one of the most dramatic experience, like watching a SCI FI movie.

Well, for the sake of getting this on the Aircraft Carriers II thread because it is quite an important thing for all STOVL carriers, and to answer your question, here goes.

Watch this video a USMC active F-35Bs exercising at the MCAS in Yuma, AZ this year.

At 43 seconds you see an F-35B hovering. At 49 they zoom out to show another F-35B landing while it hovers. At 56 seconds they zoom out again and then that hovering F-35B flies away horizontally. So yes, they can do it.

​

The aircraft is billed and designed to be a STOVL (Short take-off, vertical landing) which is primarily what the harriers do. Vertical take-off and then transition to horizontal flight from that hover takes too much fuel...but that does not mean it cannot do it.

Here's another video showing USMC test aircraft operating off of the USS Wasp during aircraft qualifications for the F-35B aboard ship. Here you will see horizontal flight transitioning to vertical (which obviously means that if they can do that, the can also do the other), and also short take off rolls from the Wasp.


[video=youtube;Ki86x1WKPmE]http://www.youtube.com/watch?v=Ki86x1WKPmE[/video]
​

Now, they will not normally go vertical take-off to horizontal flight because, as stated pure vertical take-off and then transitioning to horizontal flight eats up too much fuel...but there will be times they have to do it, either because of recovery to someplace near the front where they do not have the room to roll (either landing or take-off) because of battle damage or some other reason.

Hope this helps

Re: Aircraft Carriers II

Thanks! This is the first time I see a video showing the transition from vertical to horizontal flight by a F35B, so much smoother and effortless too, compared to Harrier. Pity it just a quick glimpse, wish there are more footage of this kind.

Re: Aircraft Carriers II

Aircraft carrier INS Vikramaditya (also Gorshkov), the Indian Navy's last vessel to be delivered by a foreign shipyard, passed with flying colours when it was operated at full throttle during exhaustive sea trials in the Barents Sea in Russia on Saturday.
The trial feedback helped overcome anxiety in New Delhi about the performance of the ship, which faltered during high-speed runs last year when its boilers failed, leaving the engines unable to produce adequate power to propel the 45,000-ton vessel.
It was a major setback as the delivery of the ship, India's second aircraft carrier, was pushed by a year.

INS Vikramaditya is the only naval warship in a foreign shipyard
After extensive repairs, the ship was back in the sea earlier this month for final delivery trials.
Navy personnel are onboard the vessel, keeping a hawk eye on the performance of the carrier which is going to be the flagship of its fleet in the coming decades.
Sources said the carrier touched a top speed of around 32 knots in wind and tide condition and the trials will continue to test capability of the retrofitted ship that will cost India around $2.3 billion.
The high-speed trials will continue for some more days to ensure that performance is stable. It will be followed by trial landings by the Mig-29K fighters.
The deck landings and take-offs were performed by the Russian pilots last year as well.
The navy hopes that its floating airbase will be ready for commissioning by the end of this year and its formal induction will take place in the early months of 2014.
INS Vikramaditya is now the only naval warship in a foreign shipyard.
All the remaining 41 warships are being constructed in domestic shipyards, in a major boost to the local shipbuilding industry

Re: Aircraft Carriers II

ok that is good news for India but now it says the handing over is early 2014, thats another delay!

what are the chances the Russians will pull a plug and delay it further

What? when did that happen? Was not the ship to be turned over to the IN in the latter part of this year?

Source...link?

All of my contacts in India continue to say...and look very much forward to...a delivery to India this year. In fact they are exepecting the vessel to depart Russian waters in the fall, beofre the ice forms, to make its way to India.

Any delay in leaving would not mean an "early 2014" handover, it would be late spring to early summer of next year becasue of the ice.

Here's another report from the Hindu on Sunday:

New Delhi
July 28, 2012

India’s second aircraft carrier, the 45,000-tonne INS Vikramaditya — a retrofitted Russian carrier formerly named Admiral Gorshkov dating back to the 1980s — has successfully completed sea trial of achieving top speed of 32 knots, reports received from Russia said on Sunday.

It will now head for the White Sea where aviation trials will be conducted, informed sources said. INS Vikramaditya was supposed to have been delivered five years ago, but the Navy will now receive it by this year-end.

The extensively modernised Soviet-era carrier had set sail from the Sevmash shipyard for its first comprehensive sea trials in the summer of 2012. Russian MiG-29K fighter pilots had successfully completed take-offs and landings on its deck. The crew tested the aircraft carrier for its top speed but it simply stopped at 30 knots. It turned out that the boilers needed better insulation, which had given way due to extreme temperatures. It took several months to fix the glitch and send the vessel for sea trials again, sources said.
The aircraft carrier, which can easily hold about 30 fighter jets and helicopters, will now go for aviation trials. “Touch-and-go exercises by fighters and various other flight profiles will also be undertaken,” officials said.

The towering 284 metre-long and 60-metre-high Vikramaditya is fitted with modern communication systems, a protective coating, a telephone exchange, pumps, hygiene and galley equipment, lifts and many more facilities. Officials said that at any given time, there would be a 2,000-strong staff on the completely remodelled aircraft carrier, which has an extended flight deck and a full runway with a ski jump and arrestor wires. The vessel has new engines, boilers, generators, electrical machinery, communication systems and distillation plants.
