The F-35 Flight Test Update in the Volume 27, Number 1 issue of Code One closed with Royal Air Force Sqdn. Ldr. Jim Schofield’s first flight, which, as it turned out, was also the program’s 1,500th flight. Since then, nine new F-35 pilots have qualified, bringing the total to forty-two pilots who have now flown the Lightning II. The growing pilot population has made significant progress testing external weapons on all three F-35 variants, accomplishing first flights with external stores, refueling inflight with external stores, and flying with asymmetric weapons loads. The team has also begun night aerial refueling of F-35 at Edwards AFB, California, and night flight testing of F-35B and F-35C variants at NAS Patuxent River, Maryland.
In the months since the last issue, the System Development and Demonstration, or SDD, test pilots have set new records for most flights in a month – 123 flights in March 2012 – and most test points in a month – 1,118 in June 2012. Through 30 June 2012, the F-35 test program had conducted 595 test flights in 2012 and accrued 4,830 test points.
The F-35 System Development and Demonstration, or SDD, test fleet surpassed 1,500 total test flights with this takeoff of F-35B BF-2 from NAS Patuxent River, Maryland. Royal Air Force Sqdn. Ldr. Jim Schofield flew the 1.2-hour mission. The milestone does not include the ninety-one test flights of AA-1, the first F-35 test aircraft.
US Marine Corps Lt. Col. Fred Schenk executed the program’s 300th vertical landing during a 1.5-hour flight in F-35B BF-1. The flight ended with a vertical landing at NAS Patuxent River, Maryland. It was BF-1 Flight 170.
An F-35A conventional takeoff and landing aircraft at Edwards AFB, California, flew the first external weapons test mission.

The two-hour flight at Edwards AFB, California, marked AF-3 Flight 96.
F-35A AF-4 piloted by US Air Force Lt. Col. Peter Vitt rendezvoused with an Air Force KC-135 tanker and successfully received fuel through the F-35's receptacle for the program’s first aerial refueling at night. The 3.1-hour sortie marked Flight 103 for F-35A AF-4.
US Air Force test pilot Lt. Col. George Schwartz became the thirty-fourth pilot to fly the F-35 when he took off from Edwards AFB, California, for a 1.2-hour mission on F-35A AF-3 Flight 103.
The F-35 Integrated Test Force at NAS Patuxent River, Maryland, completed F-35B weapons pit drop testing with the ejection of a 500-pound GBU-38 bomb from F-35B test aircraft BF-3. The ground test was the final bit of data needed to compete the first phase of testing nine different weapon combinations in the F-35’s internal weapons bays.
The F-35 test team set several new monthly program records in March, including the most test flights (123), most test flight hours (224.1), most F-35C carrier variant flights (thirty-one), and the most flight hours on a single aircraft (35.5 on F-35A AF-2).
US Marine Corps Col. Arthur Tomassetti became the thirty-fifth pilot to fly the F-35 during a 1.2-hour F-35B BF-4 mission at NAS Patuxent River, Maryland. It was his first Joint Strike Fighter flight since 30 July 2001 when he flew a test flight in the X-35B concept demonstrator. Today, Tomassetti is the vice commander of the 33d Fighter Wing Air Education and Training Command at Eglin AFB, Florida. The mission marked BF-4 Flight 105.
US Navy Lt. Christopher Tabert expanded the flight test envelope of the F-35 when he flew the first aerial refueling mission with external weapons loaded on F-35B BF-2.
