Defense Propulsion AM Exposure · NYSE: LHX
L3Harris: additive manufacturing is embedded in rocket, missile and hypersonic propulsion industrialization—not a standalone earnings story.
Through Aerojet Rocketdyne, L3Harris uses additive manufacturing in RL10, RS-25, hypersonic scramjets, tactical missiles and spacecraft propulsion. The capability reduces part count, welds, lead time and fragmented supplier steps, while qualification and rate production remain the true bottlenecks.
As of: 30 October 2026 (key metrics updated to Q3 2026; space-propulsion stake sale updated 5 October 2026; other figures as of 18 July 2026) · Profile: Diversified defense and propulsion exposure · Recommendation: None

2026-10-03 — L3Harris: AM Is Moving Into the Missile-Propulsion Scale Problem
NEXT CATALYST TO MONITOR
Serial-production evidence, qualified part families, customer approvals, disclosed volumes and whether AM becomes financially material.
Quick research snapshot
AM exposure: Low
Pure-play score: 1 / 5
Bottleneck score: 5 / 5
Evidence: Serial
Financial materiality: Emerging
Main risk: Program concentration, government funding and qualification timing.
Research verdict: L3Harris embeds additive manufacturing in propulsion and defense systems where qualification and mission assurance create high switching costs; direct AM economics remain undisclosed.
Investor read
L3Harris is benefiting from accelerating defense demand and a record backlog, while additive manufacturing supports production velocity inside propulsion programs. Q3 2026 revenue increased 7% (9% organic) to $6.06 billion, orders reached $19.3 billion (book-to-bill 3.2x) and backlog rose to a record $53.2 billion. Segment operating margin was 15.9%.
Missile Solutions revenue increased 5% to $1.057 billion with $127 million of operating income (12.0% margin); the segment’s Q3 book-to-bill was 11.8x. The Missile Solutions IPO has been postponed; on the Q2 2026 earnings call (29–30 July 2026) management said it expects to revisit the IPO in mid-2027 (Q2 2026 call transcript). The segment is supported by a proposed $1 billion Department of War convertible preferred investment.
The AM exposure has been reshaped. On 4 August 2026, L3Harris completed the sale of an approximately 60% stake in its commercial space propulsion business to AE Industrial Partners at a total enterprise value of $845 million, retaining roughly 40%; the new company is named Rocketdyne. The transaction excluded RS-25. Investors must therefore distinguish retained missile and RS-25 capabilities from space assets that moved to Rocketdyne (L3Harris, August 2026).
