The leader of Honeywell International Inc.’s aerospace group says the $15 billion operation is still wrestling with problems in its supply chain even as it’s been steadily ramping production.

“The mechanical side is still very fragmented. It’s still very non-robust,” Jim Currier, president and CEO of Honeywell Aerospace Technologies, said March 11 at the JPMorgan 2025 Industrials Conference. “There’s still a lot of lack of resiliency in the mechanical supply base. It’s an ongoing issue. It will be an ongoing issue for some time.”

Currier pointed out that Honeywell Aerospace has for 10 straight quarters increased its output despite the supply-chain snags. The business, which will be spun out as an independent company next year, last year produced organic growth of 11% that was fueled by strong demand for its products from the commercial and defense sectors.

He added that the situation with various parts makers and other suppliers is improving—albeit because Honeywell is pitching in through “investments that we’re making in buying tooling for them and the like.” On top of that, Honeywell is following the playbook of many other manufacturers since the COVID-19 pandemic and broadening the base of companies from which it buys.

“We’re doing a lot of work in terms of dual-sourcing [and] multi-sourcing many of our products to kind of unlock the capacity that exists there,” said Currier, who has led Honeywell Aerospace since the summer of 2023 after being president of Honeywell’s electronic solutions group.

On the topic of supply chains, JPMorgan analyst Steve Tusa asked if tariffs the Trump administration has put in place have the potential to raise component costs and dent Honeywell’s margins. Currier said the measures put in place so far will have a “relatively minor” impact on his team’s numbers and that Honeywell has plans in place to digest them. But he quickly added that things can change.
