A LinkedIn post shared with Lens, which links to the PJ40 page on the website of the UAE defense group EDGE, says: “Designed and manufactured in the UAE, the PJ40 turbojet engine has more than 20 sensors and several function redundancies to support dependable performance.” The post adds that integrating propulsion into missiles and UAVs means working within tight limits on space and system architecture. Lens could not open EDGE’s page, so the sensor and redundancy figures are the post’s own claims and are not independently confirmed.

What has been published about the PJ40

  • Maker: the PJ40 belongs to the portfolio of Powertech, a propulsion company EDGE launched in February 2025 (AirSpace Economy, Defence Industry Europe). Defence Industry Europe calls Powertech EDGE Group’s centre of excellence for propulsion systems for drones, missiles and uncrewed aircraft.
  • Thrust: DEFCROS News reported on November 19, 2025, from the Dubai Airshow, that the PJ40 has a “maximum continuous thrust of 450 N” and a thrust-specific fuel consumption under 40 g/kN·s. It did not give the engine’s weight, length or diameter.
  • Intended use: DEFCROS News said the group of new Powertech engines is “poised to enhance the performance of the company’s UAVs and missile systems.” Neither that report nor the others Lens read names a missile or drone that uses the PJ40.
  • Production: Lens found no report that the PJ40 is in serial production, and no price or customer for it.

The rest of Powertech’s range

According to DEFCROS News, Powertech showed at Dubai Airshow 2025 the P145i piston engine (145 hp, under 60 kg), the P80i (about 32 kg) and the P10i (10 to 12 hp, under 6 kg), the PJ40 and PJ120 turbojets, and the X550 turbofan, with a maximum thrust of 4,700 N and a weight of 105 kg, which it said was aimed at testing in early 2027.

The PJ120

Aviation Week (Steve Trimble, June 15, 2026) reported that Powertech launched serial production of the PJ120, rated at 1,200 N of thrust, about a month earlier, and displayed one of the first serial models at a show in Paris; it called the engine the company’s first move into jet propulsion. AirSpace Economy, citing that report on June 19, said the engine is meant to support EDGE’s Dark Wing precision-guided munition and its WSM cruise missile, and attributed to chief executive Marian Lubieniecki the statement that the company moved from formation to production in less than 18 months. DEFCROS News had reported in November 2025 that PJ120 production was anticipated for the third quarter of 2026 after bench tests.

What Powertech said in Poland

In a Defence Industry Europe interview published on September 18, 2026, at the MSPO fair in Kielce, Lubieniecki said: “Our main activity is building our own IP,” and that Powertech expects to have Polish suppliers and partners. The article says its turbojet work is based in the UAE and its piston-engine research and development in Italy, and lists turbojets of 450 N and 1,000 N of continuous thrust. It also says customers include other EDGE companies and buyers in the UAE and abroad, without naming any, and that no Polish investment or facility has been announced.

Where the figures differ

Defence Industry Europe lists Powertech’s larger turbojet at 1,000 N of continuous thrust, while Aviation Week and DEFCROS News give the PJ120 as 1,200 N; Lens did not reconcile them.

Notes: EDR Magazine’s report on Powertech’s Dubai Airshow range could not be opened, and a search summary says it lists further PJ40 figures, including a short-term maximum thrust, length, diameter and weight; Lens has not used them. The PJ40 is not the same engine as the PBS TJ40-G1 from the Czech Republic. Whether the PJ40 has been delivered or flown has not been reported.
