Can RTX's Survivable Communications Portfolio Support Defense Growth?

RTX's Collins Aerospace won 2025 work to provide survivable multi-band satellite communications and serve as primary subcontractor on a U.S. Navy Very Low Frequency communications and command-and-control infrastructure solution. The expanding portfolio of SATCOM, AEHF, voice and military communications systems positions RTX to benefit from demand for resilient defense connectivity in contested environments. Zacks consensus projects RTX EPS growth of 14.79% in 2026 and 7.60% in 2027; shares have gained 23.5% over the past year, although the stock trades at 2.62x forward sales versus a 2.28x industry average.

Analysis

The communications opportunity is strategically credible but unlikely to move RTX consolidated estimates without disclosed contract value, backlog conversion timing, or segment-margin data. Collins can monetize system integration across radios, terminals, cryptography and sustainment, yet this is also labor- and qualification-intensive work; near-term upside depends on mix rather than simply program awards. For RTX, the more investable question is whether defense communications can offset any aerospace supply-chain or aftermarket variability, not whether it creates a standalone earnings leg.

LHX is the cleaner public proxy for resilient communications spending: its portfolio has greater direct exposure to tactical networks, electronic warfare and mission systems, so incremental Pentagon emphasis on contested connectivity should carry higher revenue sensitivity and less conglomerate dilution. VSAT has asymmetric optionality if multi-orbit military demand improves utilization and government-service mix, but balance-sheet leverage and execution on satellite-network economics make it a higher-beta expression rather than a core defense allocation. The second-order beneficiary is not necessarily the prime contractor but suppliers of protected waveforms, terminals and classified integration; scarce cleared engineering capacity can constrain revenue recognition across the group.

Consensus risk is that resilient-connectivity procurement remains fragmented across classified budgets, continuing resolutions and long test cycles. A defense-spending headline may lift all three names over days, but meaningful awards-to-revenue conversion is more likely a 12-24 month process. RTX already embeds a premium valuation and strong operating momentum, leaving limited room for a generic capability narrative; the thesis is falsified if Collins orders/backlog do not accelerate for two consecutive quarters or if segment margin fails to improve despite higher defense mix.

Key Decisions for Investors

• Prefer a 6-12 month long LHX / short RTX pair, sized beta-neutral: LHX offers more direct mission-systems sensitivity, while RTX requires defense upside to overcome a richer embedded expectation. Reassess if RTX reports Collins defense order growth materially above LHX or if LHX cuts segment-margin guidance.
• Do not add directional RTX exposure solely on this development. Set an alert for disclosed contract value, funded backlog and Collins segment order growth; initiate only if those data support a defense revenue contribution capable of changing next-12-month consensus EPS.
• For higher-risk capital, maintain VSAT on a 3-6 month watch list rather than buy immediately. Enter only after evidence of government-service revenue acceleration and leverage improvement; downside remains substantial if network utilization and free-cash-flow conversion do not improve.
• Use any sector-wide defense-communications rally to fade indiscriminate premium expansion in RTX rather than chase it. A sustained rerating requires procurement appropriations and booked orders, not capability announcements; stop the relative-value short if RTX outperforms LHX by 10% with confirmed upward EPS revisions.
