This should be very easy to incorporate into the Blk 4 enhancements. Even if the respective loyal wingmen haven’t been fully developed or tested they should be able to design the interfaces to allow the systems, once development is finished, just plug and play.

Under Skyborg program, F-35 and F-15EX jets could control drone sidekicks

The F-35 and F-15EX fighter jets could get drone wingmen in the coming years, the U.S. Air Force’s top acquisition official revealed to Defense News.

The service is exploring ways to team Lockheed Martin’s F-35 and Boeing’s new F-15EX with the XQ-58 Valkyrie drone — a low-cost attritable fighter made by Kratos Defense — or similar unmanned platforms. Attritable systems trade attributes like “reliability and reparability” to achieve lower costs, according to the Defense Technical Information Center.

The Air Force is in discussions with Boeing and Lockheed on the prospect, and the Air Force Research Laboratory is working on the technology, Will Roper said May 21 in an exclusive interview.

“I’m very passionate about doing it, and the F-35 has a wonderful opportunity to do this as part of Block 4,” Roper said, referring to the F-35’s upcoming upgrade program. “We might also have an opportunity to do this as part of F-15EX.”

As expected the Senate Armed Services Committee has authorised an additional 16 F-35 aircraft over that request by the Administration with the specific variant numbers below.

Senate Armed Services Committee authorises 94 F-35s for FY20.

Authorizes $10 billion to procure 94 Joint Strike Fighter aircraft, an additional 16 aircraft above the administration’s request, enabling the forces to modernize and equip themselves with the most advanced and capable fifth-generation aircraft

- Includes $5.4 billion to procure 60 F-35A fighters
- Includes $1.3 billion to procure 12 F-35B fighters
- Includes $2.5 billion to procure 22 F-35C fighters

Authorizes advanced procurement to ensure that the Air Force is able to purchase the number of aircraft needed to meet the NDS in a timely fashion Encourages the Department of Defense to establish a specific plan to find cost savings for the F-35, including authorizing the purchase of material and equipment in economic order quantities, supporting the Department’s planning for multi-year procurement and block buys, and produce progress reports on achievements of specific targets.

Norwegian F-35 visited Denmark so that the local people around their AFB could get a feeling for how much sound / decibel the F-35 produce compared to F-16's.

I don't think that is a new order, just the existing additional order from last year that is being re-reported.

In line with the above Poland continues to move towards an F-35 acquisition.

Poland reaffirms interest in F-35

Poland has deepened its interest in the Lockheed Martin F-35, with the country’s defence minister indicating that it intends to purchase 32 examples of the fifth-generation fighter.

Mariusz Blaszczak says it intends to acquire the A-model variant to replace its Soviet-era RAC MiG-29 and Sukhoi Su-22 aircraft under the Harpia programme.

"Fifth-generation fighters are already on the horizon. Today we sent a [letter of request], an offer inquiry, to our partners from the United States regarding the purchase of 32 F-35A aircraft, along with a logistics and training package.

The Hill based F-35 Fighter wings have certainly been touring the world, the latest is a deployment to Italy.

Air Force deploys F-35 squadron to Italy for exercises, training

The U.S. Air Force has deployed a squadron of F-35A Lightning II fighter jets, airmen and equipment to an air base in Italy for exercises and to conduct training with other Europe-based aircraft.

The squadron, which includes the fifth-generation fighter plane, arrived Friday at Aviano Air Base from the 388th and 419th Fighter Wings at Hill Air Force Base, Utah. as part of a Theater Security Package. The jets and personnel will remain in Europe for several weeks, according to a U.S. Air Force news release.

The Burlington F-35 saga continues.

Many More Homes Are Inside High-Decibel Areas on New F-35 Sound Maps

The arrival of the louder F-35 military jets at Burlington International Airport will nearly triple the number of homes affected by high noise levels, according to sound maps released Tuesday.

A total of 2,640 dwelling units will be affected by noise at or above 65 decibels in 2023, compared to 976 on sound maps for 2015.

The new projections, based on computer modeling, suggest high-decibel noise will affect larger portions of Winooski and Williston, and slightly less of certain parts of South Burlington.

It will also affect small parts of Burlington and Colchester, and a corner of Essex with no homes. A total of 2,655 acres will be within the 65 decibel zone in 2023, according to the projections.

That's according to a 164-page noise exposure study that has been eagerly awaited by residents in the flight path, including some who oppose having the F-35s at the airport.

No surprise given the production rate that this has occurred. It will only take another three years before the numbers double again now.

Number of F-35s Built for USAF Eclipses Number of F-22s

Lockheed Martin delivered its 196th F-35A Joint Strike Fighter to the Air Force this week, surpassing the total of 195 F-22s—test and production—that it delivered to the service between 1996 and 2011.

The 196th F-35 will be based at Hill AFB, Utah, home of the first operational USAF F-35 squadrons. The first F-35A was delivered to the Air Force in 2006.

More than 395 F-35s have been built, including variants produced for the Marine Corps, Navy, and foreign partners and customers.

The only mention I can find of it is that the Air Force is using the A to replace the Tornado, and the B to replace the AMX , which is used for CAS. Perhaps they expect to employ some sort of FARPs like the USMC does with their Bees to keep them closer to the front and the troops they support. Recall the Harrier began life as an RAF, not RN plane.

Lockheed Martin's F-35 Lightning II Program is providing Italy with the 5th Generation fighter that will ensure security for the next generation. Italy is a partner on the F-35 program and has signed the Production, Sustainment and Follow-On Development phase. Initially signed up in 2001 to buy 160 aircraft, but by 2011 the number was down to 131. In February 2012 Italy further reduced its purchase to 90 CTOL and STOVL variant aircraft. The Italian Air Force had envisaged buying 40 STOVL JSFs to replace its AMX fighter bombers, alongside 69 conventional JSFs to replace its Tornado aircraft. If the Italian Air Force dropped its B-purchase, Italy would still try to buy 22 of the F-35B to replace Harrier jump jets flown off the aircraft carrier Cavour.

I see. Didn't know the B was well suited for CAS. Or that the AF had flights from the Cavour (always thought it was Navy ground). Thank you.

The Pentagon is threatening to cut Turkey out of the F-35 fighter jet program.


"In carefully choreographed steps, Acting Defense Secretary Patrick Shanahan released a letter he sent Thursday to the Turkish minister of defense, Hulusi Akar, outlining the path the Pentagon is taking to stop Turkey from participating in the F-35 fighter program. The steps include halting the training of Turkish pilots on the advanced fighter jets starting July 31.The United States has already stopped delivery of F-35 parts to Turkey, a North Atlantic Treaty Organization member that has built increasingly close ties in recent years to Moscow. Turkey has bought four F-35s, but the jets remain in the United States.Separately, officials told reporters at the Pentagon that Turkey would not be allowed to take part in previously scheduled meetings on the weapons system."

It's going to be very interesting to see who blinks first.

There has been a period of DOD ineptness that fortunately seems to be receding. For the navy the DDG-1000, the LCS series, and the Ford carriers show the worst of it. The DDG-1000 cost over 8B apiece including development and clearly do less than Arleigh Burke's, systems like its 5 inch gun was designed for shells costing $800k apiece (why not more SM missiles), the LCS series is in search of a mission, and the Ford went high risk with its electric catapult, new arrester system, and elevators using linear motors. The electric catapult was right to be included as it eliminated all steam except in the machine room, but the current arrester and elevator systems worked just fine thank you. The cats are crazy - no isolating disconnects on the power so one can be worked on with the others operating.

Now it comes out that the Fords are not ready for the F-35s but those are the planes to be used. Just inept.

The Navy’s first F-35C squadron, VFA-147, is expected to deploy aboard USS Carl Vinson (CVN-70) in 2021, USNI News previously reported. Carl Vinson is currently in drydock at the Puget Sound Naval Shipyard and Intermediate Maintenance Facility in Bremerton, Wash.

The Vinson is 20 miles from my house, the subs at Bangor I can occasionally see out my window.

Second phase of Blk 4 upgrades have been awarded.

Lockheed Martin awarded $1.8 Billion for F-35 Block 4 software development

The U.S. Navy has awarded Lockheed Martin $1.8 Billion for the second phase of the F-35 Lightning II Block 4 pre-modernization program for the Air Force, Navy, Marine Corps; and non-U.S. Department of Defense (DoD) participants.

According to Lockheed Martin, underpinning the F-35’s capabilities is more than 8 million lines of software code. From flight controls to fusing together the F-35’s sensor data to form a clear and comprehensive picture of the battlespace, software is essential.

F-35 Block 4 comprises more than 50 improvements to counter both air- and ground-based threats emerging from China and Russia. These enhancements increase F-35 pilots’ recognition and detection ranges, enabling greater overall targeting performance. Some source reported that the Block 4 upgrades will be “80 percent” software.

A new YouTube video tour gives a 360 degree view of the F-35 Joint Strike Fighter. The tour, hosted by Commander Tony “Brick” Wilson, was uploaded by defense contractor and F-35 manufacturer Lockheed Martin. Wilson points out some of the less well known aspects of the fifth generation stealth fighter, including the aircraft’s armament capability, sensors, and engine performance.

I'm not sure this is as big an issue as is being reported. Contractually I would think it was more costly to change the contract for F-35 specific changes compared to those occurring post delivery, especially given all current in service ships have to be modified anyway.

The Navy's newest supercarriers can't carry its new F-35 stealth fighters, and Congress is not happy about it

The new Ford-class supercarriers are being delivered to the US Navy without the ability to deploy with the service's new stealth fighters, and lawmakers have decided to put a stop to it.

It's very difficult to get something like an aircraft carrier cheaply and quickly and have it work well. In the case of the Ford-class carriers, the Navy program is facing cost overruns, delivery delays, and missing capabilities.

The Navy has been accepting unfinished aircraft carriers that are lacking critical capabilities, such as the ability to deploy with fifth-generation fighters.

The service has been planning to complete the necessary work after delivery to skirt the caps imposed by Congress to keep costs from soaring, USNI News reported this week. The workaround ultimately results in higher costs in the long run.

The USS Gerald R. Ford (CVN-78), which should be delivered back to the fleet this fall, currently lacks the ability to deploy with F-35s, and the USS John F. Kennedy (CVN-79), which is still in the works, will not be able to deploy with F-35s either, at least not upon initial delivery.

That's a big problem for Congress.

"CVN-79 will not be able to deploy with F-35s when it's delivered to the Navy," a congressional staffer said this week, telling reporters that it's "unacceptable to our members that the newest carriers can't deploy with the newest aircraft."

The Navy argues that while the newest carriers may not be ready to carry F-35s upon delivery due to the need for additional modifications, none of which require significant redesigns to the ship, they will be ready to go by the time the air wing is stood up and the carrier-based F-35Cs are ready for operational deployment aboard the Navy's new flattops.

The "F-35C modifications for CVN-78 and CVN-79 are currently scheduled for a future post-delivery modernization maintenance period that will occur prior to the planned F-35C operations on those carriers," Captain Daniel Hernandez, a spokesman for the Navy acquisitions chief, told Business Insider.

The two follow-on Ford-class carriers, CVN-80 and 81, "will be constructed with those modifications made during construction and will not require a post-delivery modification," he further explained.

Not sure if the partner nations have a bulk buy purchase going for the F135 or not similar to the multi-year F-35 from Lot 12.

Pratt & Whitney awarded $3.2B for 233 F-35 engines for U.S., allies

Pratt & Whitney has been awarded a $3.2 billion contract to supply 233 propulsion systems for F-35 fighter jets to the United States and allies.

More than half the contract for the F-35 Lightning II engines are for allied militaries, with nearly 150 engines designated for non-Department of Defense participants and foreign military sales customers, the Pentagon announced Friday.

The deal designates 56 F135-PW-100 propulsion systems for the U.S. Air Force, 10 F135-PW-100 for the Navy, 24 F135-PW-600 for the Marine Corps, and 125 F135-PW-100 and 18 F135-PW-600 for non-Department of Defense participants and foreign military sales customers.

Largest deal in history and impressive cost reductions for the aircraft. The great thing to note here is this is still technically Low Rate Initial Production and the US is not participating in the bulk buy. Hence greater savings will come in the future from both US Bulk buys as well as continued cost reduction from suppliers and production learning from LM.

$34B = Biggest Procurement In History As Lockheed, DoD Handshake Deal for 478 F-35s

Pentagon acquisition czar Ellen Lord’s statement says it: “This is a historic milestone for the F-35 Enterprise, and marks the largest procurement in the history of the Department. The $34B agreement for F-35 Low Rate Initial Production Lots 12-14 will see the delivery of 478 F-35 aircraft, 157 for Lot 12, in support of our U.S. Military services, our Partner Nations, and our Foreign Military Sales customers.”

Yes, ladies and gentlemen, the biggest conventional weapons program in history has just set the record for a single deal in, well, probably, any country at any time. For perspective, the entire Australian defense budget for 2019 came in at about $27.52 billion US.

Here are some of the more important details from today’s announcement. Top of the list is the fact that the flyaway price of the F-35A will drop below $80 million one year earlier than planned in Low Rate of Initial Production (LRIP) Lot 13. Lord said in the statement that the Pentagon will reap an estimated 8.8 percent in savings from Lot 11 to Lot 12 for F-35A’s, and an average of 15 percent reduction “across all variants from Lot 11 to Lot 14.”

The issue appears to be operating at AoAs above 20 degrees which is important for the WVR envelope and according to the report a fix is planned for the 3rd quarter.

When US Navy and Marine F-35 pilots most need performance, the aircraft becomes erratic

The U.S. Navy’s and Marine Corps’ F-35s become unpredictable to handle when executing the kind of extreme maneuvers a pilot would use in a dogfight or while avoiding a missile, according to documents exclusively obtained by Defense News.

Specifically, the Marine short-takeoff-and-vertical-landing variant and the Navy’s carrier-launched version become difficult to control when the aircraft is operating above a 20-degree angle of attack, which is the angle created by the oncoming air and the leading edge of the wing.

Pilots reported the aircraft experiencing unpredictable changes in pitch, as well as erratic yaw and rolling motions. The documents identify the issue as a category 1 deficiency and define it as something that limits the aircraft’s performance in such a way that it can’t accomplish its “primary or alternate mission(s).” In this scale, category 1 represents the most serious type of deficiency.

...

https://www.defensenews.com/smr/hidden- ... s-erratic/

More at the link.

Sagely words at the end of the article though,

An active-duty naval aviator who reviewed the documents for Defense News said the issues are reflective of an aircraft that packed in a lot of new technology, adding that, historically, all new jets have had problems.

“That document looks like growing pains for an aircraft that we tried to do a whole lot to all at once,” the aviator said. “You’re going to see that if you dig back at what Super Hornets looked like for the first few years. Go back in the archives and look at Tomcat — think about that with the variable sweep-wing geometry, the AWG-9 Radar.

"There was a lot of new technology incorporated into the aircraft, and there are always going to be growing pains.”

In line with the article above below are the deficiencies that the program is currently dealing with. The majority are related to the B/C versions and not the more common A. Most of these are well known and have fixes planned or being implemented.

The Pentagon is battling the clock to fix serious, unreported F-35 problems

Over the past several years, U.S. Defense Department leaders have gone from citing technical problems as their biggest concern for the F-35 program to bemoaning the expense of buying and sustaining the aircraft.

But the reality may be worse. According to documents exclusively obtained by Defense News, the F-35 continues to be marred by flaws and glitches that, if left unfixed, could create risks to pilot safety and call into question the fighter jet’s ability to accomplish key parts of its mission:

...

The 13 deficiencies include:

- The F-35’s logistics system currently has no way for foreign F-35 operators to keep their secret data from being sent to the United States.
- The spare parts inventory shown by the F-35’s logistics system does not always reflect reality, causing occasional mission cancellations.
- Cabin pressure spikes in the cockpit of the F-35 have been known to cause barotrauma, the word given to extreme ear and sinus pain.
- In very cold conditions — defined as at or near minus 30 degrees Fahrenheit — the F-35 will erroneously report that one of its batteries have failed, sometimes prompting missions to be aborted.
- Supersonic flight in excess of Mach 1.2 can cause structural damage and blistering to the stealth coating of the F-35B and F-35C.
- After doing certain maneuvers, F-35B and F-35C pilots are not always able to completely control the aircraft’s pitch, roll and yaw.
- If the F-35A and F-35B blows a tire upon landing, the impact could also take out both hydraulic lines and pose a loss-of-aircraft risk.
- A “green glow” sometimes appears on the helmet-mounted display, washing out the imagery in the helmet and making it difficult to land the F-35C on an aircraft carrier.
- On nights with little starlight, the night vision camera sometimes displays green striations that make it difficult for all variants to see the horizon or to land on ships.
- The sea search mode of the F-35’s radar only illuminates a small slice of the sea’s surface.
- When the F-35B vertically lands on very hot days, older engines may be unable to produce the required thrust to keep the jet airborne, resulting in a hard landing.

Re: F-35 news thread

Wed Jun 12, 2019 7:44 pm

LM has released a response to the DefenceNews reporting above. As expected most of the issues are either rectified, have a plan in place to remedy or are not actually a concern for the program.

Lockheed Martin Comments on Defense News Reporting

Below, please find comments from Lockheed Martin on improvements underway addressing the items identified in Defense News’ June 12 article series.

Overall Comment

The F-35s today are meeting or exceeding performance specifications and delivering unprecedented capability and safety compared to legacy fighter aircraft. The feedback we receive from F-35 pilots is exceptional – and any pilot who has flown a legacy jet consistently relays back that if they are being sent in to harm’s way – they want the F-35, every time.

These issues are important to address, and each is well understood, already resolved or on a near term path to resolution. We’ve worked collaboratively with our customers and we are fully confident in the F-35’s performance and the solutions in place to address each of the items identified.

ALIS Sovereign Data Management

ALIS meets data sovereignty requirements. Late last year, some customers requested that the F-35 enterprise develop additional capability to enable more data control.

We rolled out the additional Sovereign Data Management tool to international F-35 operators earlier this year, which allows them to manage aspects of their data that is sent to the F-35 Hybrid Production Support Integration (HPSI) team – and early feedback from the fleet is positive. It is also important to note that this has no impact to mission performance or safety of flight.

Part Inventory Data

This is a major focus at Lockheed Martin and we are implementing several actions including automation and enhanced supplier accountability processes that are delivering improved performance. Through automation, data is now vetted and validated automatically versus manually, improving speed and ensuring accurate EEL information is present before a part is delivered to the flight line.

With these new actions and related efforts, we’ve seen a 50 percent reduction in EEL and other action requests since 2017. We are confident this is on a path to resolution, which will reduce maintenance times and increase readiness rates. It is also important to note that this has no impact to mission performance or safety of flight.

Cockpit Pressurization

The cabin pressure performance today meets the specified requirement. There have been no reported cases of barotrauma in the fleet and our joint government and industry analysis shows that risk of barotrauma is minimal and that there is no imminent safety issue.The enterprise is always reviewing pilot experience improvements and we have an update that performed successfully in lab testing and will now be flight tested for future integration, based on customer timing priorities.

Cold Weather Battery Performance

This was identified during extreme cold weather testing at negative 30 degrees or below at Eielson Air Force Base, Alaska in February 2018. The probability of the issue reoccurring on aircraft in the operational fleet is very low and with minimal impact to safety of flight or operational performance.

We have developed an update to the software and the battery’s heater control system to resolve this issue – and this updated software is available for users today to load on their aircraft in the event they will be conducting extreme cold weather operations. This will also cut into production in the 2021 timeframe. We are confident this is on a path to resolution.

F-35B and F-35C Horizontal Tail Durability at Sustained Supersonic Flight

The F-35B and C deliver on all performance requirements. The potential for tailboom or horizontal tail damage during prolonged supersonic speeds was found in the highest extremes of flight testing conditions that are unlikely replicated in operational scenarios. In fact, there have been no cases of this issue occurring in the operational fleet. Additionally, this is not identified as a safety of flight concern.

We implemented a change to the coatings on the horizontal tails and tail boom beginning in Lot 8 that increases durability and resolves this concern. This update allows the F-35B and C to deliver on all performance requirements with no tail boom or horizontal tail damage concerns.

F-35B and F-35C Angle of Attack (AOA)

We’ve implemented an update to the flight control system that is planned for integration in the third quarter of this year – and we expect this item to be resolved or downgraded.

Hydraulic Lines Ruptures Caused by Blown Tires

The F-35 has two redundant hydraulic lines and there has never been a case of both lines being impacted, which ensures safe operations. Brake control software updates and pilot training have alleviated this concern and resulted in a significant drop in blown tire events. Additionally, we made minor adjustments to the location placement of hydraulic lines on the F-35C that has resolved the potential for line breaks.

We believe the item is resolved and are standing by for additional customer feedback.

Helmet “Green Glow”

The U.S. Navy continues to fly with their current helmet, demonstrating their confidence in the system, and pilots with greater than 50 night landings operate with the current Gen II helmet at night. The improved Gen III helmet has already been designed, tested and is now being qualified for use. The first few of these new helmets have been delivered and we anticipate the upgraded helmets will resolve both the green glow and night vision conditions identified.

Additionally, as camera and OLED technology advances rapidly, we expect the F-35 helmet to continue to deliver unprecedented levels of situational awareness for pilots and only improve further over time.

Radar Sea Search

The F-35’s current radar sea search function meets the enterprises’ required specification.As we modernize the F-35, we are bringing enhanced search capabilities, which represent an increase from the original requirements, and we stand ready to integrate the upgrade in the future, based on customer priorities and direction.

Thrust limits on hot days

We are supporting the Joint Program Office and Pratt and Whitney, and they can best address questions related to the F-35’s engine, which is Government Furnished Equipment to Lockheed Martin.

It seems to be the "beat on Airplane Manufacturer's Month", between these reports on the F-35 as well as Boeing's travails. Most reports have a snippet of information blown out of proportion. It seems that perfection is suddenly demanded, well no plane is perfect.
