Right, that's what I remembered. But still, we see no purple dots past 0.95M for any variant even though we know it has been done. The remarkable part to me is the collection of dots around 0.3M at 40,000ft.

At least there is a remedy for this situation being implemented to the satisfaction of all (when it is finished - one hopes).
DoD inspector general slams F-35 program office for allowing Lockheed to manage government property
15 Mar 2019 Valerie Insinna

"WASHINGTON — The F-35 Joint Program Office has not adequately tracked government property leant or leased to Lockheed Martin and its subcontractors, an oversight that a new investigation by the Defense Department’s inspector general said could impact readiness. Building the F-35 Joint Strike Fighter requires the use of government property such as materiel, special tooling like molds used to form the jet’s structure and unique test equipment.

Over the lifespan of the program, the F-35 JPO has not followed the mandated procedures used to manage government-furnished property, or GFP, and instead depended on Lockheed and its subcontractors to keep track of such equipment, stated a DoD IG report released Friday. [see link in 'marsavian' post immediately above here]

“As a result, the DoD does not know the actual value of the F‑35 property and does not have an independent record to verify the contractor‑valued government property of $2.1 billion for the F‑35 program,” the report said. “Without accurate records, the F‑35 Program officials have no visibility over the property and have no metrics to hold the prime contractor accountable for how it manages government property.

“The lack of asset visibility restricts the DoD’s ability to conduct the necessary checks and balances that ensure the prime contractor is managing and spending F‑35 Program funds in the government’s best interest and could impact the DoD’s ability to meet its operational readiness goals for the F‑35 aircraft.”...

...The IG, in its report, said it was satisfied with the corrective actions proposed by the JPO, but that it would review their implementation at a later date. Creating a record of government property will not be as simple as copying over Lockheed Martin’s record.

Lockheed estimates there are 3.45 million pieces of government property used for the F-35 program, and that equipment is worth an estimated $2.1 billion. However, its records are not written to the same standard that the Defense Department mandates. For instance, federal regulations require that government records keep track of the contract number associated with a given piece of GFE, while Lockheed did not include that information. Other data recorded by the company — such as the name of a part or its quantity — were incomplete by Pentagon standards."

The horror -- the squeal of the gummint bean counting bureaucrats...

However, its records are not written to the same standard that the Defense Department mandates.


LM prolly saving the gummint $$ by not dotting every i to the nth degree. Expect costs to rise once the bureaucratic bean counters get their fangs into the program.
Take an F-16, stir in A-7, dollop of F-117, gob of F-22, dash of F/A-18, sprinkle with AV-8B, stir well + bake. Whaddya get? F-35.

GAO - WEAPON SYSTEMS ANNUAL ASSESSMENT [2 page summary PDF attached - part of text excerpted below etc.]
May 2019 GAO

"F-35 Program - Technology Maturity and Design Stability
All of the F-35’s critical technologies are mature and the baseline engineering drawings are complete for all three aircraft variants. The program office completed the final development test flights for the baseline program in April 2018, but continues to address over 900 deficiencies identified with the aircraft’s performance prior to the end of development testing. For example, the program is developing a new helmet mounted display, which will resolve an existing green glow effect that can distort a pilot’s vision during night time carrier landings. Program officials expect installation of some of the new displays in 2019. The program office is also testing and integrating software updates to resolve other deficiencies, but it did not fully resolve over 800 other deficiencies prior to the start of operational testing. The program obtained a waiver from the Under Secretary of Defense for Acquisition and Sustainment to start operational testing prior to fully resolving these deficiencies. Program officials stated that they expect to continue resolving these deficiencies through the start of full rate production in October 2019.

Program officials continue to identify and address technical risks, some of which are specific to individual variants of the F-35. For example, we reported last year that a problem with the F-35’s main fuel throttle valve caused the aircraft to move suddenly and without stopping until the engine is shut down. In 2018, the program implemented software changes to fix this problem. Also, across all variants, pilots have reported experiencing extreme pressure in the cockpit during certain flight maneuvers. Contractor representatives told us they have identified the root cause of the excessive cockpit pressure and will implement a minor hardware change in 2019 to address the issue. Recently, following the crash of an F-35B in October 2018, the program grounded the F-35 fleet to inspect all of its engines. An investigation determined a manufacturing defect caused an engine fuel tube to rupture during flight, resulting in a loss of power to the engine. The program office reported that it identified 117 aircraft with the same type of fuel tubes that it must replace. According to program officials, the grounding generally did not impact the delivery of the aircraft, as the contractor has provided replacement fuel tubes that were installed on a majority of the affected aircraft by the end of 2018.

Production Readiness
As of December 2018, the prime contractor has delivered 264 production aircraft. Since the start of production, F-35 contractors have refined their production processes to improve manufacturing efficiency and quality. However, the prime contractor has identified quality control and late radar deliveries as the top production risks in the program. For example, because of supplier identified limitations, the prime contractor continues to fix gaps between adjacent aircraft surface panels attached to the airframe. These fixes are needed to meet low observable (stealth) performance requirements. The contractor is working with its supplier to resolve the problem through improved production processes as the program approaches its full-rate production decision in October 2019...."

Japanese Ministry of Defense official report on the F-35A crash that occurred April 9th, 2019: https://www.mod.go.jp/asdf/news/houdou/H31/20190610.pdf

The second document is my semi-manual interpretation of the report - I do not speak / read Japanese, but what I've done is used Google translate on paragraphs, individual sentences, phrases and even words or characters to get a better understanding of what the actual meaning is behind the Japanese text, then I've re-written it in English as closely as possible while maintaining half-decent grammar and edited it back into the original PDF, including with the graphics on the last 2 pages:

Thanks for that 'Dragon029'. One can become accustomed to the left descending turn initial sensation and then (without looking at or believing instruments) think that this 'state of flight' is straight and level. Then to continue left descending turn one makes even more left descending turn rates erroneously - this is one example of SD IF I have imagined correctly.

OOPs should have kept reading because there are diagrams showing the steps etc. RoD increases dramatically - yikes!

Point a jet towards the surface (engine at idle/ some rpm/ full)? WATCH OUT!
"...4. Measures:
(1) For the likely cause of "spatial disorientation", implement measures:
A. Spatial awareness education for F-35A pilots.
B. Training with spatial awareness training equipment and simulators for F-35A pilots.

(2) For the very unlikely, but still possible, causes of G-LOC unconsciousness,
or problems with aircraft engine control, maneuvering or electrical systems:
A. Education for all F-35A pilots on loss of consciousnes due to G-LOC.
B. Perform special inspections of F-35A fighters (engine controls, steering and electrical systems)…."
