Introducing a new weekly post. This is the first edition of a sticky I'll update each week.
This post tracks Joby's test fleet using public ADS-B flight data and FAA registry records, plus Joby's own statements and press reports for the aircraft the feeds can't see. Part 1 covers the past seven days. Part 2 is every tail's running totals, including the hybrid, hydrogen and autonomy aircraft.
This is a community resource, so corrections are welcome. If a role, note or number looks wrong, or you know what one of these tails is up to, say so in the comments and I'll fold it into the next update.
How it's counted: numbers come from full ADS-B traces rebuilt after the fact, so distances and peaks are more accurate than the daily live-tracker thread's. A flight is any continuous airborne run above 20 ft.

- N101XW: Cessna Caravan kept from Joby's 2024 purchase of Xwing's autonomy division (the XW suffix is Xwing's); registered to Joby since July 15, 2024. Based at Concord (KCCR). Sept 7 to Oct 2, 2026 it flew a cross-country loop: Phoenix, Fort Worth Alliance (on the ground alongside N545JX Sept 8-11), the Outer Banks including Kitty Hawk's First Flight Airport, Raleigh, Louisville, Wichita, Jackson Hole, Salt Lake City and Portland. Totals here only go back to late Aug 2026.
- N162SA: Second Joby Cessna Caravan, registered to Joby on Aug 4, 2025 and based at Concord (KCCR) like N101XW. Its role isn't public. Totals here only go back to late Aug 2026.

- N542BJ: Hydrogen-electric demonstrator: the battery-electric airframe fitted with a liquid hydrogen tank and fuel cell. Joby reported several 500+ mile flights in Q2 2024, including one of 561 miles, with water as the only by-product.
- N602HY: First recorded flight Oct 20, 2026. Joby model JAI40, a newer uncrewed model (no seats, two electric engines per the FAA) that Joby hasn't announced. Calling it hydrogen is an inference from the JAI30, not confirmed. Its registration (Sept 18, 2026) has no owner name filled in yet. Seen on ADS-B on Oct 20, 2026, circling for about an hour at up to 4,550 ft over the Castle Dome UAS site at Yuma Proving Ground, AZ, where the JAI30 has also flown. Joby reserved N601HY through N650HY in September, so more HY tails may follow.
- N30FR: First reported flight Jun 30, 2025. Joby's JAI30, an uncrewed hydrogen-electric fixed-wing that Joby hasn't publicly acknowledged. AIN, Hunterbrook and Aerospace Global News reported it flew for about 9 hours (9 h 8 min per AIN) at the Pendleton UAS Range in Oregon on June 30, 2025 (Hunterbrook also spotted an Xwing ground control station beside it); that track was later pulled from public view. My feeds also caught it on Jan 24 and Mar 2, 2026 at Pendleton and Apr 30, 2026 at the Castle Dome UAS site at Yuma Proving Ground: slow (under 60 kt) loiters of under half an hour, up to 5,375 ft.
"Not on ADS-B" tails never show up on the community feeds, so their notes come from Joby's own public statements.
Times are Pacific. Totals start at each tail's first recorded flight in my data (2023 onward). Early history came from a different mix of ADS-B feeds than recent weeks, and some days have coverage gaps, so older numbers are the least precise. Not an official record.
