The 2018 DOT&E report is out and it's only 14 pages as compared to 30 in 2017 and 60+ in 2016.

Http://www.dote.osd.mil/pub/reports/FY2 ... f35jsf.pdf

Primary takeaway:
2017 report had "Over 1000" open deficiencies
2018 report stated 102 as of May 2018, a 90% reduction.

• Assessment

- Based on F-35A gun testing through September 2018,
DOT&E currently considers the accuracy of the gun, as
installed in the F-35A, to be unacceptable.

- F-35A gun accuracy during SDD failed to meet the
contract specification. Although software corrections were made to the F-35 mission systems software to improve the stability of gun aiming cues, no software or hardware corrections have yet been implemented to correct the gun accuracy errors.

- Investigations into the gun mounts of the F-35A revealed misalignments that result in muzzle alignment errors. As a result, the true alignment of each F-35A gun is not known, so the program is considering options for re-boresighting and correcting gun alignments.

- During air-to-air gun testing, F-35A operational test pilots received intermittent “unsafe gun” cockpit alerts while attempting gun attacks. These alerts occurred with two different aircraft; the root cause is under investigation.

- F-35B and F-35C air-to-ground accuracy results to date
with the gun pod have been consistent and meet the
contract specifications. They do not show the accuracy
errors of the internal gun on the F-35A.

Recommendations:

• The program should:
...
5. Determine the cause of the accuracy problems with the F-35A gun firing and implement a solution for increasing gun accuracy for the fielded aircraft.

This is an 'amazing' development, an 'engine' running in a hangar, who said the USN are too cautious with F-35C [from DOTE].
"...The Navy approved the use of the F-35 Integrated Power Package (IPP) in the hangar bay for maintenance
purposes, on an interim basis, just prior to the SGR testing onboard CVN 72. This approval will enable more efficient maintenance during deployments, increasing the options for providing electrical power and cooling air to aircraft undergoing maintenance. Squadrons will use temperature sensing devices to ensure that the IPP exhaust, which vents upwards on the F-35C, does not damage hangar bay overhead equipment, cabling, and structure while in use...." p.5

My Google-Fu is failing me. I know we have seen charts that showed conditions flown by all three F-35 variants with multi colored dots for different test conditions. Anyone have a copy of that?

Sorry Spaz, I wasn't too clear. This was effectively a flight envelope diagram made up of colored dots. IIRC blue dots were clean test points, purple were external AA, green were external A-G, and the B had extras to represent Mode IV I believe. There were three diagrams side by side for A, B, and C.

Try look into F-35 Aerodynamic Performance Verification 6.2018-3679.pdf

Lockheed Martin Aeronautics Company, Fort Worth, TX, 76101, United States of America

Also some of this charts are in your comparison thread.

Dragon also has something here
