The increase shifted the company's backlog mix toward defense, which accounted for about 48% of the total, compared with about 41% in the second quarter.1–2

RTX received Tomahawk and AMRAAM multi-year undefinitized production contracts during the quarter. Its results release did not disclose their values, leaving their contribution to the defense backlog increase unspecified. Chief executive Chris Calio cited more than $81 billion in new awards across commercial and defense combined.1

RTX raised its full-year adjusted sales outlook to $97.0 billion to $97.5 billion, following an increase in July.1–2 It also raised its 2026 organic sales growth forecast to 10% to 11%.1

The company-wide defense backlog expansion accompanied slower reported sales growth at Raytheon: the segment's third-quarter sales grew 14% year over year on both a reported and organic basis.1–2 Reported year-over-year growth was 18% in the second quarter.2 RTX attributed the third-quarter sales increase to higher volume on naval programs and land and air defense systems, including Patriot, Standard Missile and Tomahawk.1

Missile Defense Agency awards Raytheon multiyear SM-3 IB contract worth up to $6.3 billion

The Missile Defense Agency award carries a $4.4 billion base value. It is undefinitized, so work can begin before terms, specifications or price are agreed.

The Missile Defense Agency awarded Raytheon a noncompetitive, multiyear contract on Oct. 7 to manufacture and assemble Standard Missile-3 Block IB interceptors, with a total value of $6.3 billion including options.2 RTX says the award is part of Raytheon's recent agreements with the Department of War and supports urgent replenishment of an interceptor first used in combat in 2024.3

That link runs back to February. Breaking Defense reported that the department and Raytheon signed a framework agreement in February designed to pave the way for this multiyear deal, and that under the agreements Raytheon would accelerate SM-3 IB production.4–5 RTX said at the time that the agreements would span up to seven years once contracts were finalized, according to Breaking Defense.5 With both option years, this contract's five-plus-two-year span reaches that outer bound.1

The department's case for the contract runs through the suppliers beneath Raytheon. It says the deal forces capital allocation "directly into assembly lines, solid-rocket motor suppliers, and critical domestic sub-tier vendors." Michael Duffey, the Under Secretary of War for Acquisition and Sustainment, said it "breaks sub-tier manufacturing bottlenecks."1

As an undefinitized contract action, the award authorizes Raytheon to begin work immediately in Tucson, Ariz., and Huntsville, Ala.1 Neither the department's announcements nor Raytheon's said how many missiles the contract buys.1–3

The milestone to watch is definitization, the agreement on or determination of terms, specifications and price that converts the award into a definitive contract.6 At award, $454 million in fiscal 2026 procurement funds was obligated against the $4.4 billion base. Funding actions on contract HQ0851-27-C-E001 will show the pace of any further obligations.2
