This is the most powerful commercial jet engine currently flying on an operational airliner.
The GE90-115B was built by GE Aerospace specifically for the Boeing 777-300ER. It weighs around 8.3 tonnes, has a 3.25 metre wide fan and produces up to 512 kN (115,000 lbf) of thrust from a single engine.
To understand the sheer scale of that output, it produces roughly 2.7 times the thrust of the F135 jet engine powering the F-35, the most powerful fighter engine currently in service.
The enormous fan at the front uses just 22 carbon fibre composite blades with titanium leading edges. At maximum thrust, it pulls in roughly 1.4 tonnes of air every second, with nearly 90% bypassing the core rather than passing through the combustor.
At around 150 knots during takeoff, its 512 kn of thrust corresponds to roughly 39.5 MW of propulsive power, or in automotive terms around 53,000 hp from one engine.
And it burns roughly 4-5 kg of jet fuel every second at maximum power conditions.
Two of these engines are enough to power a fully loaded 777-300ER weighing more than 350 tonnes. Even if one engine fails after the critical point during takeoff, the aircraft is certified to continue the takeoff and climb on the remaining one GE90 engine.
Each engine costs around $35-40 million. More than 2,500, GE90s engines have been built, and the GE90 family has accumulated nearly 130 million flight hours.
And this is precisely why companies like GE Aerospace remain so difficult to displace in jet engines.
There is never one breakthrough. GE spent roughly $2+ billion developing the GE90, chasing small gains across hundreds of systems, efficiency, materials, reliability and component life.

Quand vous irez à Rome, profitez-en pour faire un détour par Ostia Antica.
Ce parc archéologique à 30 km à l'ouest de la capitale italienne, représentait l'ancienne ville portuaire de la Rome antique.
Fondée au VIIe siècle avant J.-C., elle offre des vestiges magnifiques.
Mexico doesn't just have a Post Office - it has a Postal Palace.🇲🇽
The Palacio de Correos de México was completed in 1907 and is one of the world's most beautiful postal buildings.
Michelangelo hated painting. He considered himself a sculptor.
Yet, he created one of the world’s greatest masterpieces out of sheer, unyielding spite.
Believe it or not, the commission to paint the Sistine Chapel was actually a TRAP because - 🧵1/
Detail of the Golden Throne of Tutankhamun, c. 1332-1323 B.C.
The golden throne of Tutankhamun was discovered in 1922 by the British archaeologist Howard Carter. It was found beneath a hippopotamus funerary bed in the antechamber of the Tomb of Tutankhamun.
The luxurious armchair is distinguished by the complexity of its technique and an abundance of details. Two projecting lions’ heads protect the seat of the throne, while the arms take the form of winged uraei or rearing cobras wearing the double Pschent crown of Egypt and guarding the cartouche names of the king.
Queen Ankhesenamun holds a salve-cup and spreads perfumed oil on her husband’s collar in a typical Amarna style scene, the sun disc Aten shines above the royal couple. At the time it was made, their names were Tutankhaten and Ankhespaaten.
The scene shows one of the most famous and intimate scenes in art history: the young king appears sitting and being regaled with an ointment by his wife Ankhesenamun.
The king wears a composite crown and a broad collar, and the queen wears a diadem. The bodies and wigs of both of them are inlaid with exquisite coloured glass, and their linen robes are silver.
From the Tomb of Tutankhamun (KV62), Valley of the Kings, West Thebes.
