(Source: Defense-Aerospace.com; posted Dec 10, 2018)
PARIS --- The F-35 Joint Program Office officially kicked off its Initial Operational Test & Evaluation (IOT&E) phase on Dec. 6, 16 months late compared to the schedule announced two years ago and 5 months late compared to the date announced in Dec. 2017.

IOT&E was due to begin in August 2017, and was then successively re-scheduled to mid-September and then mid-November as the program had not completed the required upgrades and repairs for the Block 3F aircraft.

It also is not clear how long the IOT&E phase will last.

JPO’s Dec 6 statement says it will be completed in “late summer 2019,” which assumes a duration of nine or ten months, but as late as January 2018 it was due to last 13 months. No explanation has been provided as to why it is being cut short by 4-months.

The IOT&E phase will be carried out with 23 Block 3F aircraft of different versions, including:
-- 6 US Air Force F-35A Conventional Take-Off and Landing (CTOL) variants;
-- 2 Royal Netherlands Air Force F-35A CTOL aircraft;
-- 6 U.S. Marine Corps F-35B Short Take-Off Vertical Landing (STOVL) aircraft;
-- 3 Royal Air Force F-35B STOVL aircraft;
-- 6 US Navy F-35C Carrier Variants (CV)

The F-35 Lightning II program reached another major program milestone with the official start of formal F-35 Initial Operational Test and Evaluation (IOT&E) this week.

Starting this week and continuing through late summer 2019 all three F-35 Air System variants (A/B/C) will be field tested, under realistic combat conditions, for the purposes of determining the weapons systems’ operational effectiveness and operational suitability for combat.

IOT&E is designed to fully evaluate the complete air system as well as identify technical and operational areas for improvement. The independent Director of Operational Test and Evaluation (DOT&E) and Joint Strike Fighter Operational Test Team (JOTT) will execute IOT&E with our U.S. Services, United Kingdom, Dutch and Australian partners participating. All test events will be conducted at U.S. Military testing ranges and installations.

Following the evaluation, the Department will have the required data to share with our Partners and to inform our “Milestone C” acquisition decision, leading to formal entry into full rate production at the end of 2019.

“The start of formal operational testing is a significant milestone for our entire F-35 Enterprise,” said Vice Adm. Mat Winter, F-35 Program Executive Officer. “It is the culmination of years of technical, programmatic and operational work and dedication from our joint government and industry team. I am extremely proud of our team’s commitment to testing excellence and dedication to providing our warfighter affordable, effective capabilities for mission success.”
