Scott C. Donnelly
Chairman, President and Chief Executive Officer at Textron
Thanks, David, and good morning, everyone.
Our businesses closed out the year with another solid quarter with strong margin performance and cash generation. Throughout the year, our teams worked to mitigate supply chain challenges to deliver products for customers. At Aviation, while we entered the year with an expectation of a book-to-bill of 1:1, solid order flow and customer demand across our product portfolio resulted in year end backlog of $7.2 billion, an increase of $782 million.
Textron Aviation Defense delivered 13 T6 aircrafts for the year, up 10 from a year ago. During 2023, solid aircraft utilization within the Textron Aviation product portfolio resulted in a 6.5% growth in aftermarket revenues. At Bell, revenues in the quarter were up driven by higher commercial and military revenues. On the commercial side of Bell, we over 91 helicopters in the fourth quarter, up from 71 in last year's fourth quarter. For the full year, we delivered 171 helicopters in 2023, down from 179 in '22. Higher military revenues reflected the continued ramp on our FLRAA program. On the FLRAA program, Bell completed the installation of the ITEP engine on the 360 Invictus. Team continues to conduct integration activities and prepare the aircraft for initial ground runs in 2024.
Moving to Textron Systems. Revenue and margin were flat with last year's fourth quarter. During the quarter, systems delivered the last detailed design and construction craft on the Ship-to-Shore Connector program following the successful completion of acceptance trials.
Moving to Industrial. We saw higher revenues in the quarter, driven by higher volume at Kautex and favorable pricing in specialized vehicles. For eAviation, Textron delivered 135 aircrafts during the year, up from 61 in 2022. Also at eAviation, during the quarter, the Pipistrel Velis Electro was selected to participate for a trial period to explore operational and training uses for this all-electric aircraft as part of Agility Prime Air Force's vertical lift program.
Summary, in 2023, the year -- we had a strong year across all of our business. We continue to execute on our growth strategy of ongoing investments in new products and programs to drive organic growth and margin expansion. During the year, Aviation announced the new Cessna Citation Ascend at EBACE and the Citation CJ3 Gen2 at NBAA. In May, Aviation delivered the first passenger variant of the Cessna SkyCourier for Lanai Airlines servicing Hawaiian Islands. In the third quarter, Aviation announced the new fleet agreement with NetJets for up to 1,500 aircrafts over 15 years, including longitude, latitude and the newly announced Ascend, extending our 40-plus year relationship. In October, Aviation delivered the 100th Cessna Citation Longitude.
At Bell, we began work on the FLRAA program in April. The team continues to increase activity on the program, ramping up engineering resource, contracting with key suppliers and ordering long-lead materials. At Textron Systems, we advanced the future tactical unmanned aircraft system competition and are now one of two remaining competitors down from the initial FLRAA. Systems also continued to win a land vehicle programs, advancing to the next phase of the Army's XM30 program as part of Team Lynx and was selected as one of four competitors to build RCV-Light prototypes for the Army. At Textron Specialized Vehicles, we introduced the new street-legal E-Z-GO Liberty LSV powered by our ELiTE lithium-ion battery system.
At Kautex, in 2023, we announced the first Pentatonic order from an automotive OEM for thermoplastic composite underbody battery protection skid plate, establishing Kautex as a supplier to the expanding battery-electric vehicle market. At eAviation during the year, we began system-level integration of the first Nuuva prototype, our hybrid electric unmanned cargo VTOL aircraft in preparation for first flight in 2024. As we closed out 2023, manufacturing performance was trending positively with improvements in labor productivity and supplier deliveries.
Looking to 2024 at Aviation, we are projecting growth driven by increased deliveries across all product lines and higher aftermarket volume. At Bell, we're projecting revenue growth in 2024 on higher military revenues from the FLRAA program and higher commercial revenues from increased deliveries. At Systems, we are expecting slightly higher revenue as new programs continue to ramp. At Industrial, we're expecting flat revenues as growth of specialized vehicles is offset by lower-than-expected volume Kautex.
At eAviation, we plan to continue investments in the development of technologies and products, supporting sustainable flight solutions for unmanned cargo, next-generation electric trainers, eVTOL and general aviation. We also expect higher aircraft deliveries at Pipistrel. With this overall backdrop, we're projecting revenues of about 14.6 billion, up 7% from 2023 for Textron's 2024 fiscal year. We're projecting adjusted EPS in the range of $6.20 to $6.40. Manufacturing cash flow before pension contributions is expected to be in the range of $900 million to $1 billion.
With that, I'll turn the call over to Frank.
