Air TransportBoeing targets 63 737 jets a month with fourth assembly line in Everett
Boeing plans to raise monthly production of its 737 jet to 63 aircraft by opening a fourth assembly line in Everett, Washington, expanding manufacturing beyond its long-time base in Renton, company executives said.
The new line, known internally as the North Line, is expected to open in mid-2026 and will be used to assemble the 737 MAX 10, the largest variant of the single-aisle family. Boeing has begun hiring and training workers in Everett to staff the facility.
The expansion forms part of Boeing’s longer-term plan to lift 737 output from current levels toward 63 aircraft a month over the coming years. The company is in the process of increasing production from 38 to 42 jets a month.
Boeing expects suppliers to support further increases of about 15% over the next 18 months, which would bring production to around 47 aircraft a month in 2027, according to company executives. That timeline is later than some industry expectations, after suppliers were previously told to prepare for a faster ramp-up.
The planned peak rate of 63 aircraft a month remains below Airbus’s stated objective of producing 75 A320-family jets monthly, highlighting the gap between the two manufacturers in the narrowbody market.
The Everett line will mark the first time the 737 is assembled outside Renton, ending decades of single-site production for Boeing’s best-selling aircraft.
Boeing has sought to stabilize its manufacturing system after years of safety, quality and supply-chain disruptions. Chief executive Kelly Ortberg has said production increases will proceed in measured steps, with rate changes spaced at least six months apart.
The 737 MAX competes directly with the Airbus A320neo family, which dominates global single-aisle aircraft orders and deliveries.
