    This is not the “1st” time the F-35B used it’s gun in flight. In fact, the article’s source actually relates to the F-35B finishing it’s airborne gun testing. It’s first use of the gun in the air was back in Feb.

    Norway defense plan reveals hidden costs of F-35 procurement.

    Norway F-35 “Upgrade”

    lol, I guess they thought they were getting Blocks 4,5,6,7, etc for free?

    Btw, am I the only one who is missing the “quote” reply button… Or did I miss the announcement that it was being removed?

    The importance of datalinks in a WVR LOAL engagement are mostly to make sure that the AAM properly discriminates between Red & Blue in a furball, especially if the targets is using flares or DIRCM. The later would require GPS to ensure that it has the best chance of maintaining a good track of the target.

    don’t shoot the messenger.

    np, I did not mean to make it sound like I was….

    btw, While the weight restrictions have been lifted, only one F-35A has been modded for the fixes. The plan is most likely to mod the training jets first in order to get light-weight pilots into the pipeline and have the front-line jets done by the time those pilots finish with training.

    That story just points to the official press release which says testing complete and does not say anythgin about “first time”

    https://www.dvidshub.net/video/525055/naval-aviation-history-f-35b-stovl-airborne-gunfire-testing-complete

    170508-N-ZB537-004 The Salty Dogs of Air Test and Evaluation Squadron (VX) 23’s Pax River Integrated Test Force (ITF) made aviation history Monday, May 8, 2017 when they completed airborne gunfire testing for the F-35B Short Takeoff and Vertical Landing (STOVL) variant. U.S. Navy video by Dane Wiedmann/Released.

    The whole “first time” thing is clearly “click bait”.

    Here is a story from back in February of the F-35B firing it’s gun in the air for the 1st time.

    It’s not he “first time”, the story says that airborne testing is “complete” which means that the F-35B has been doing it for quite a while.

    Air Force to Release F-35 Weight Restrictions

    this is the safest ejection seat I’ve ever flown,” said Brig. Gen. Scott L. Pleus, the F-35 Integration Office director.

    http://www.af.mil/News/Article-Display/Article/1182874/air-force-to-release-f-35-weight-restrictions/

    WASHINGTON (AFNS) — Air Force leaders recently removed the restriction that kept pilots weighing less than 136 pounds from flying the F-35A. The restriction was imposed in 2015 due to concerns about the risk during ejections in a portion of the flight envelope.

    After rigorous testing to ensure the escape system works reliably and safely in all planned conditions and across all pilot weights, three distinct modifications were implemented. A switch was installed on the seat that slightly delays parachute deployment at high speeds and decreases parachute opening forces for lightweight pilots. Additionally, a head support panel has been mounted on the rear risers of the parachute to prevent the pilot’s head from moving backwards during an ejection. Finally, the overall helmet weight has been reduced through both the reduction of internal strapping material and the removal of an additional external visor, which decreases injury risk during parachute opening.

    “I have personally briefed every single F-35 pilot in the United States Air Force about these changes to their ejection seat, and I’m confident our pilots are no longer concerned with the safety of the F-35 ejection system. I’ve flown in this seat myself and believe, with these modifications, this is the safest ejection seat I’ve ever flown,” said Brig. Gen. Scott L. Pleus, the F-35 Integration Office director.

    In July 2015, during the manufacturer’s ongoing testing, analysis identified an unacceptable risk of neck injury during parachute deployment/opening for pilots weighing less than 136 pounds. The requirement is for the seat to be certified for any pilot weighing between 103 and 245 pounds.

    Air Force headquarters and wing leadership took immediate action to ensure pilot safety and work with the manufacturer to meet requirements for the seat. The F-35 Joint Program Office has been working in concert with contractors to develop options to reconfigure the ejection system.

    The new ejection seats are already being retrofitted into the existing fleet, and the lightweight helmets are available in pre-production now, while full production starts later this year. The Air Force has received more than 100 F-35As to date, trained more than 400 pilots and accumulated more than 40,000 flight hours.

    F-35 Block Buy (Long Lead items) is issued.

    Long Lead items for Lot 12 (130 AC) that covers the US & all Partners and also covers Long Lead for Lot 13/14 (110 AC) that covers just Partner nations.

    Lockheed Martin Corp., Lockheed Martin Aeronautics Co., Fort Worth, Texas, is being awarded a not-to-exceed $1,377,002,000 advance acquisition contract for long-lead time materials, parts, components, and effort for 130 low-rate initial production Lot 12 F-35 Lightning II aircraft for the Air Force, Navy, Marine Corps, non-U.S. Department of Defense (DoD) participants, and foreign military sales customers. In addition this contract provides long-lead time materials, parts, components, and effort for 110 Lot 13 and 14 F-35 Lightning II aircraft for the non-U.S. DoD participants and foreign military sales customers. Work will be performed in Fort Worth, Texas (30 percent); El Segundo, California (25 percent); Warton, United Kingdom (20 percent); Orlando, Florida (10 percent); Nashua, New Hampshire (5 percent); Nagoya, Japan (5 percent); and Baltimore, Maryland (5 percent), and is expected to be completed in December 2018. Fiscal 2017 aircraft procurement (Air Force, Navy, Marine Corps); non-U.S. DoD participant; and foreign military sales funds in the amount of $1,377,002,000 are being obligated at time of award, none of which will expire at the end of the current fiscal year. This order combines purchases for the Air Force ($315,500,000; 23 percent); Marine Corps ($128,925,000; 9 percent); Navy ($43,509,000; 3 percent); non-U.S. DoD participant ($524,446,000; 38 percent), and foreign military sales customers ($364,622,000; 27 percent). This contract was not competitively procured pursuant to Federal Acquisition Regulation 6.302-1. The Naval Air Systems Command, Patuxent River, Maryland, is the contracting activity (N00019-17-C-0001).

    What’s the value of bringing down a radar-less T-38? Frankly, that’s a job for an F-4 Phantom II, not for a Raptor..

    Most OpFor has never had any real BVR capability (A-4s, T-38s, etc). As the article said, they were there to simulate BVR opponents and to take advantage of any Blue Force mistakes.

    Here is another oddity… the Wiki entry for APG-81 has a different array which is likely bigger in count & size to the know APG-81 array. The number of T&R rows is more than the known array and the monting points are different.

    https://upload.wikimedia.org/wikipedia/commons/thumb/e/ec/AN-APG-81_Antenna%2C_2005_-_National_Electronics_Museum_-_DSC00393.JPG/414px-AN-APG-81_Antenna%2C_2005_-_National_Electronics_Museum_-_DSC00393.JPG

    https://en.wikipedia.org/wiki/AN/APG-81

    If anyone want to, here is the 3k x 4k version of the above pic:
    https://upload.wikimedia.org/wikipedia/commons/e/ec/AN-APG-81_Antenna%2C_2005_-_National_Electronics_Museum_-_DSC00393.JPG

    T&R design clearly points to a Northrop Grumman product as they are almose identical to the APG-81 T&R design.

    Looks like it came from the National Electronics Meuseum.

    If we assume SpudmanWP counted the prongs , not the gaps ( which he said he didn’t ) then you can deduce number by 1 for each collume, there are around 50 collumn of T/R modules on APG-81. So 1626 – 50 = 1576 T/R modules, still higher than CAPTOR-E number

    The “valley” represent’s the T&R module, not the “hill”.

    Here is a commercial x-band AESA array that clearly shows the radiating element in the “valley”. Notice that each side “ear” of the element creates a large “hill” between each “valley” except for the ends which only have a “half-hill”, just like the APG-81.

    Um… am I the only one who sees that it’s a Superhornet “F-18E” and not a “Classic Hornet”? (typo?)

    Yeah it’s plug and play with their UAI or whatever it’s called.

    Nic

    If they are waiting for UAI then they would have to wait for Block 4.x since UAI will not be part of F-35 till then.

    Once UAI is in the F-35, integration only takes 3-5 months and much of that time is spent doing separation certification and employment parameter tweaking.
