The engine order book at the end of June was just six engines lower than the record set at the end of September last year.
At the end of June there were 102 fewer single-aisle engines on order than at the start of the year but 332 more widebody engines and these pushed the total number of engines on firm order up. There are currently 230 more engines on order than at the start of the year. The First Half engine order intake was a big improvement on 2024 and the number of First Half engine installs was the largest, for a First Half, since 2019.
Despite a new aircraft backlog record in June, the engine order book at the end of the month was six engines lower than the record set at the end of September last year. The First Half aircraft order intake was the second largest for a First Half in the last 10 years and the engine order intake was an improvement on last year but less than half the First Half 2023 intake. Aircraft deliveries in the First Half of this year, as well as engine installs, were the largest for a First Half since 2019.
The First Half 2025 in brief:
At the end of June there was a new record aircraft backlog made up of 13,477 single-aisles and 2,772 widebodies. The current aircraft backlog is 582 larger than at the end of June last year and 1,787 aircraft larger than at the end of June 2023. The engine order book reached a record 30,058 at the end of the September last year and then dropped for a number of months before improving in May and June of this year. There are now 30,052 engines on firm order, 230 more than at the start of the year and 266 more than at the end of June last year.
The First Half aircraft order intake this year was the second largest for a First Half since 2013 when there were orders for 1,580 aircraft. The First Half engine order intake this year (1,398 engines) was nearly 500 engines larger than the First Half 2024 intake but was over 1,700 engines lower than in the First Half of 2023. Part of the problem here is that a large number of aircraft have been ordered this year without engine selections. The number of To Be Decided engines has gone from 1,806 at the start of the year to 2,438 at the end of June.
The First Half aircraft delivery and engine install totals this year were the largest for a First Half since 2019 which shows that there has been some measure of recovery this year. The difference between the First Half 2019 and the First Half this year amounts to 32 aircraft and 80 engines. What is important to remember in this context is that aircraft delivery numbers in the First Half of 2019 had dropped due to the 737 MAX being grounded. Compared to the First Half 2018, this year there have been 97 fewer aircraft deliveries and 212 fewer engine installs. 2018 was the record year.
The Engine Order Book:
There were over 30,000 engines on order once again at the end of June.
There have only ever been over 30,000 engines on order four times, three of which were last year. The number of engines on firm order dropped in October last year from the record set at the end of September and continued to drop until May this year. May had the first order book gain of 2025. There was a further order book gain in June taking the order book to 30,052 engines, very fractionally lower than the record and not much larger than the figure at the start of this year.
There were orders for 518 engines in June, the largest intake in a single month since December 2023. The June intake took the Second Quarter intake to 906 engines, considerably more than in Q2 last year but over 1,700 fewer than in Q2 2023. The First Half order intake came to 1,398 engines, again considerably more than the intake last year but less than half the intake in the First Half of 2023.
The single-aisle engine order intake this year has been relatively modest; 832 engines gross but 632 net. Also, the number of single-aisle engines on firm order has dropped by 102 engines since the start of the year and by 150 since the end of June last year. What has pushed the total engine order book up has been the widebody engine order intake. So far this year there have been orders for 566 widebody engines, the largest for a First Half since 2018 when there were orders for 624 widebody engines.
The number of widebody engines on firm order has only dropped a handful of times in the last two years and the current total of 4,948 engines is the largest since May 2016 when there were 12 more on firm order than there are now. In the last 12 months the widebody engine order book has grown by 416 engines (9.2%) and in the last two years the order book has grown by 1,264 engines, or 34.3%.
Not that long ago the widebody engine order book reached the low point of 3,150 engines. That was in November 2022. The current figure is nearly 1,800 engines higher, a 57% gain.
Shares of the single-aisle engine order book: CFM had 19,310 engines on firm order at the end of June which is a 76.9% share of the single-aisle engine order book and 44 more engines on order than at the start of the year. There were 19,286 LEAP engines on order at the end of June, 76.8% of all single-aisle engines on firm order. (There are only 24 CFM56 engines currently left on order.) Pratt & Whitney had 5,790 single-aisle engines on firm order at the end of June (all GTF engines) and the PW1100G is the third largest single-aisle engine program in terms of order book size with 4,424 on order.
Shares of the widebody engine order book: At the end of June, GE had a 50.9% share of the widebody engine order book with a total of 2,518 engines on firm order, 44 more than at the start of this year. The GE9X has had the largest widebody engine order book gain this year with an increase of 140 engines. Pratt & Whitney currently has 134 PW4062 engines on order, 14 fewer than at the start of the year. Rolls-Royce currently has 302 more engines on order than at the start of the year with all three of the company’s engine programs recording order book gains. The Trent 7000 is up 120 engines, the Trent 1000 is up 54 engines and the Trent XWB now has 128 more engines on order than at the start of the year. Rolls-Royce currently has a 46.4% share of the widebody engine order book.
