JSF/JCA Winner: F-35 Lightning II
In 2001 the F-35 was declared as the winner of the US Department of Defence JSF (Joint Strike Fighter) competition. The UK name for this aircraft is the JCA (Joint Combat Aircraft)

The objective of the F-35 is to provide a set of 3 different, yet similar, aircraft capable of multi-role combat. To reduce production, research and maintenance costs each of the 3 airframes required 70-90% similar airframes.

The F-35 is a joint program between the US (Lockheed Martin & Northrop Grumman) and UK (BAE Systems). It is the largest defence programme with initial customers having a requirement of around 3,000 aircraft.

The 3 "variants" of the F35:

  • F-35A - To be used by the USAF (United States Air Force). Designed as a CTOL (Conventional Take Off & Landing) providing mainly air-to-air (with the possibility for air-to-ground) combat. 
  • F-35B - To be used by the USMC (United States Marine Core). This variant is STOVL (Short Take Off & Vertical Landing). 
  • F-35C - To be used by the US Navy and RN (Royal Navy). This variant is CV (Carrier Variant) and uses catapults to launch the aircraft, and arrestor wire to bring the aircraft to a stop during landing.

Originally the F-35B was the choice of aircraft for the MOD (Ministry of Defence) but this was later changed to the F-35C after the October 2010 SDSR (Strategic Defence & Security Review). This is mainly due to the Carrier Variant being able to operate off the planned CVF Aircraft Carriers.

Powerful electromagnetic catapults can propel the jet to take-off speed within seconds giving the aircraft the capability to take increased fuel and weapons on missions

The F-35C sports larger wings (~45% larger than the F-35A/B), tough arresting gear and a new catapult system. The large wing area means that more fuel can be held and therefore longer missions are possible.  F-35C also has slats, larger horizontal tails and control surfaces to allow for reduced low-speed landings. The wings can be folded when landed to save space on board the carrier.

The F-35C can be loaded with more fuel and ordnance than F-35B due to the launch technique which means the carrier variant will be able to operate to distances up to 3,000km which is around 1,000km further than the STOVL variant.

Using a recaptcha to prove you're not a script

Spam is a scourge for all websites, so webmasters have to take measures to ensure that thier sites are protected. One of the best ways of protecting a site is to create a task on the signup/commenting forms, that only a human can do with reasonable accuracy. CAPTCHAs ("Completely Automated Public Turing test to tell Computers and Humans Apart") as shown below ask you to read some distorted text, which the average computer finds very hard to do.

You can use the control buttons in the captcha to help you as follows.

Refresh Button - If you're having trouble working out the words to enter, you can request a new set of words, without having to submit your form by pressing the refresh button.

Audio Button - Alternatively if you have trouble with your vision, you can use the audio CAPTCHA, pressing the audio button will playback a set of words for you to type in.

The words you enter need not have the same uppercase/lowercase as the images shown, the system ignores case, likewise it only uses the characters a-z and 0-9, so you dont have to enter any odd characters, accents etc.

 
Please prove you're a real person and not a computer program up to no good.
