U.S. Rep. Mike Turner walked the floor of Sierra Nevada Corp.'s Dayton campus this week, touting a company that now employs more than 400 people locally and has grown from a single building to seven since landing a $13 billion Air Force contract. The visit comes as Turner, a Republican seeking a 13th term in Congress, faces a competitive reelection fight in Ohio's 10th Congressional District against Democrat Kristina Knickerbocker.
The tour was reported by the Springfield News-Sun, centered on Sierra Nevada's work modifying aircraft under a $13 billion Air Force contract renewing the E-4B Nightwatch fleet — the aging jets tasked with protecting U.S. leadership in the event of nuclear war. Sierra Nevada Corp. senior vice president and Dayton site executive Mark Williams said Turner has been a huge ally to Sierra Nevada, according to the same report. Turner, for his part, said the company's Dayton campus exemplifies investment and job growth in the defense sector, per the newspaper's account.
Sierra Nevada's rapid buildout tracks with a broader pattern of aerospace investment taking root around Wright-Patterson Air Force Base. In May 2024, the company agreed to purchase five Boeing 747-8 passenger airliners from Korean Air for roughly $674 million, aiming to convert them into the Air Force's next-generation E-4C Survivable Airborne Operations Center fleet, according to Air & Space Forces Magazine. Sierra Nevada became the sole bidder on that contract after Boeing, the original builder of the E-4B Nightwatch, was eliminated from the competition in December 2023 for declining to accept a fixed-price development deal, per the Defense Security Monitor.
From One Building to Seven
The company's physical footprint has expanded fast to keep pace with the workload. Sierra Nevada's second 100,000-square-foot facility at Dayton International Airport was operational in September 2024, while the company broke ground on two more hangars, according to ExecutiveBiz. By August 2025, the company had begun flight testing the first converted E-4C aircraft at its Aviation Innovation and Technology Center at Dayton International Airport, as reported by the The Aviation Geek Club, with testing scheduled to continue through 2026 across Dayton and Wichita facilities.
Turner has also supported Sierra Nevada modification work and contracts involving Air Force KC-46 and C-17 aircraft, per the Springfield News-Sun's reporting. The newspaper notes that Sierra Nevada chose the Dayton community for jobs outside Wright-Patterson itself, adding another layer to the region's workforce; the Wright-Patterson workforce has approximately doubled during Turner's time in Washington.
Building the Workforce Pipeline
To keep up with hiring needs, Sierra Nevada Corp. and Sinclair Community College launched the SNC-Sinclair Academy in June 2026, an employer-designed training program aimed at addressing local shortages of aviation maintenance technicians, according to Avi-Go. The academy adds to a growing list of regional investments; Hoodline has previously reported on Joby's $500M buy of Dayton-based defense contractor Resonant, part of a wave of aerospace expansion near the base.
Wright-Patterson Air Force Base itself remains the economic anchor of the district, contributing more than $16.6 billion annually to the regional economy and standing as Ohio's largest single-site employer, according to the Official Website of U.S. Representative Mike Turner. The Springfield News-Sun reports the base now has about 38,000 military and civilian workers, and Turner said work continues toward a $135 million advanced materials research lab and a separate space-focused intelligence facility at the base, for which the Space Force approved $22.2 million in architecture and engineering funding this year.
A Tighter Race Than Usual
Turner is not cruising to a 13th term unopposed. Ohio's 10th Congressional District, which includes Montgomery County, Greene County and northeast Butler County including Middletown, will put three candidates before voters on the November 3 general election ballot: Turner, Democrat Kristina Knickerbocker, and Libertarian Tom McMasters, per the Springfield News-Sun.
Knickerbocker's campaign has said Turner has defended the war with Iran and tariffs that increased costs for Ohio families, according to the Springfield News-Sun. A July 2026 poll from the House Majority PAC showed Turner leading Knickerbocker 48% to 41% among likely voters in the district.
Libertarian candidate Tom McMasters has said members of Congress should spend more time in their districts and less time with professional lobbyists in Washington, D.C., the Springfield News-Sun reports. Meanwhile, Jon Husted visited Sierra Nevada Corp. on September 3, adding another notable name to the parade of officials touring the campus in recent weeks.
Defense Bill Still Stuck in Congress
The visit comes with Congress approaching the end of the federal fiscal year on September 30 without a finished defense appropriations bill in hand. The House passed its defense policy package for fiscal year 2027 in July 2026, and the House Armed Services Committee moved its version of the appropriations bill in June 2026 — legislation that, per Committee Chairman Mike Rogers, featured authorization of $1.15 trillion in discretionary funds and a $1.5 trillion topline investment, allowing for up to 4.5% of the nation's gross domestic product. Still, the House has yet to pass a defense appropriations bill, and the Senate stalled its own work on the matter over the summer, according to the Springfield News-Sun's reporting. The newspaper also notes the National Defense Authorization Act itself does not provide budget authority or appropriations — a distinction that leaves the funding fight unresolved even as Sierra Nevada's Dayton operation keeps expanding.
