L3Harris Technologies, Inc.

L3Harris Technologies is a defense electronics prime contractor — space systems, communication systems, intelligence, and aviation/electronic warfare. Post-Aerojet Rocketdyne acquisition (closed July 2023), L3Harris also manufactures tactical solid rocket motors (SRMs) for missiles and interceptors through the Aerojet facility.

L3Harris Technologies — defense electronics prime contractor with added tactical solid rocket motor manufacturing (post-Aerojet Rocketdyne acquisition, closed July 2023). Core business: space systems, communication systems, intelligence & reconnaissance, aviation/electronic warfare platforms. Aerojet segment: tactical SRM production for US intercept systems, land-attack missiles, and advanced air-breathing propulsion.

L3Harris Communications & Spectrum Dominance (CSD) segment — the sovereign mission-critical communications backbone for US and allied forces. CSD designs and builds software-defined tactical radios (Falcon family: AN/PRC-117G, AN/PRC-152/163, NGC2 Manpack), submarine communications systems (Virginia/Columbia-class through 2033), electronic warfare/spectrum superiority platforms, and integrated C4ISR networks. This is NOT commodity radio hardware — it's an encrypted, software-defined, multi-waveform ecosystem with decades of qualification, certification, and interoperability lock-in.

L3Harris’ Communications & Spectrum Dominance segment is the sovereign mission-critical communications stack: software-defined tactical radios, resilient waveforms, encryption/networking, and adjacent spectrum-superiority equipment for U.S. and allied forces.

L3Harris is a defense electronics prime contractor with space, communications, intelligence, aviation/electronic warfare, and post-Aerojet tactical solid rocket motor manufacturing.

L3Harris Technologies — defense prime spanning (1) Missile Solutions (MSL): end-to-end propulsion, sensing, guidance, munitions (post-Aerojet); (2) Communications & Spectrum Dominance (CSD): software-defined tactical radios, resilient waveforms, EW; (3) Space & Mission Systems (SMS): ISR, space systems, mission networks. The investable thesis concentrates in TWO bottlenecks: the US tactical solid-rocket-motor (SRM) supply duopoly and the sovereign mission-critical comms switching cost.

L3Harris Technologies — defense prime across three segments: Space & Mission Systems (SMS ~49% of revenue), Communications & Spectrum Dominance (CSD ~33%, sovereign mission-critical comms), and Missile Solutions (MSL ~18%, post-Aerojet tactical solid-rocket-motor production). The investable bottleneck thesis lives in TWO of the three: the US tactical SRM duopoly (MSL) and the sovereign comms certification wall (CSD).

L3Harris Technologies is a U.S. defense prime and national-security technology company. It operates in four reportable segments after the July 2023 Aerojet Rocketdyne acquisition:

L3Harris also reports full-year net income of $1,221M and diluted EPS of $6.37 on the same filing basis. Source: L3Harris FY2023 Form 10-K, consolidated statements of operations; accession no. 000020274-24-000006; filed 2024-02-20; accessed 2026-05-07.

The company is heavily defense and intelligence-oriented. The largest segment, Integrated Mission Systems, contains missionization, electronic warfare, intelligence, surveillance, reconnaissance, maritime, and C2 systems. Space & Airborne Systems contains space payloads, missile warning, ground systems, airborne sensors, and classified intelligence systems. Communication Systems contains software-defined tactical radios, SATCOM terminals, and networked communications. Aerojet Rocketdyne is rocket and missile propulsion.

This mix matters because the segments have different contracting structures. Communication Systems has a higher proportion of production contracts and foreign military sales; Space & Airborne Systems has classified and space programs with long qualification cycles; Aerojet Rocketdyne carries fixed-price defense and space propulsion contracts.

L3Harris monetizes through U.S. Government prime contracts, subcontracts, foreign military sales, and direct commercial sales. The 10-K discloses revenue recognition under ASC 606 with fixed-price, cost-reimbursable, and time-and-material contract types. Exact contract-type mix is not restated here and is needs primary source validation from the 10-K revenue note.

Consolidated net margin is derivable from the two verified figures:

\[

\text{Net margin} = \frac{\text{Net income}}{\text{Revenue}} = \frac{1{,}221}{19{,}419} = 6.29\%

GAAP operating income and operating margin are not restated in this note because I could not independently parse the exact 10-K income-statement line in this session. The company’s segment-level operating income and unallocated corporate expenses require reading the segment note directly; the exact consolidated operating margin is needs primary source validation unless pulled directly from the 10-K income statement and segment note.

L3Harris typically does not emphasize gross margin; it emphasizes segment operating margin, adjusted EBITDA, and free cash flow. The 10-K includes segment operating income and unallocated items; do not rely on third-party numerator or denominator adjustments without checking the filing.

The payers are primarily:

• U.S. Department of Defense, including Army, Navy, Marine Corps, Air Force, and Space Force program offices.
• U.S. intelligence agencies and classified national-security customers.
• NASA and other U.S. civilian agencies.
• Allied governments through U.S. Foreign Military Sales and direct commercial sale channels.

These customer classes are drawn from the 10-K’s business discussion and customer-concentration risk factors, not from investor-relations paraphrases.

The 10-K describes customer concentration at the agency level, not by commercial counterparty. The filing names U.S. Government customers and identifies the U.S. Government as the largest customer category. It does not normally disclose non-government end-customer names because much of the revenue is classified or government-directed. Therefore, the top customers named from the filing are the U.S. Department of Defense, the U.S. intelligence community, NASA, and allied foreign governments.

CSD segment Q2 2026: $1,943M revenue (+4% YoY); H1 2026: $3,798M; segment operating margin 26.9% (+230 bps YoY) — the highest margin across all three LHX segments, indicating structural pricing power. Total LHX Q2 2026: $5,881M (+8%), record backlog $42B (1.2x book-to-bill), FY26 guidance raised to $23.2–23.7B. CSD contributes ~33% of total revenue but ~55% of segment operating income due to margin superiority.

Q2 2026 CSD revenue was $1,943M (+4% YoY), operating income was $522M (+14% YoY), operating margin was 26.9% (+230 bps YoY), and ending contractual backlog was $9,031M. At the company level, Q2 revenue was $5,881M (+8% YoY) and FY26 guidance was raised to $23.2B–$23.7B.

Q1 2026 revenue was $5.7B (+12% YoY, +15% organic); orders were $7.8B; book-to-bill was 1.4x; backlog hit a record $40.7B; operating margin was 11.4% (+120 bps).

Q2 FY2026 (10-Q filed 07-30): revenue $5.881B (+8% YoY), diluted EPS $3.13 (+28%), record backlog $42B (book-to-bill 1.2x, 6th straight quarter >1.0x). CSD Q2 revenue $1.943B (+4%), operating income $522M (+14%), margin 26.9% (+230bps) — the highest-margin segment. Missile Solutions Q2 revenue $1.054B (+14%), with Propulsion Systems +$85M on key missile/munitions program ramps. FY26 guidance raised to $23.2–23.7B revenue / $11.80–12.00 EPS.

Counter-UAS interceptor ramp (Coyote Block 3, AIM-9X, GMLRS) + expanding DoD missile inventory post-Ukraine → LHX/Aerojet SRM capacity = documented bottleneck. SASC testimony: 18-36 month motor lead times. LHX + Northrop/NGIS = US tactical SRM duopoly. Every US interceptor needs their motors.

SRM duopoly (LHX + Northrop/NGIS) in US tactical rocket motor supply. Every US interceptor (PAC-3 MSE, SM-6, AMRAAM, GMLRS, Coyote Block 3, AIM-9X variants) requires tactical SRM from one of these two suppliers. Pentagon acknowledged SRM production bottleneck post-Ukraine (Senate Armed Services Committee testimony, FY24/25 NDAA SRM capacity expansion funding). LHX/Aerojet motor lead times 18–36 months. Counter-UAS ramp (Coyote Block 3 procurement acceleration, AIM-9X missile stock buildup) directly pulls LHX SRM capacity. Record backlog $40.7B (Q1 2026) = 7.1 years of revenue @ current run rate — validates demand extension beyond 2026–2027.

Sovereign military communications are the highest-switching-cost infrastructure in defense. Once a force adopts Falcon radios + waveforms + crypto + networking stack, replacement requires: (a) crypto recertification (NSA Type 1, 18-36 months), (b) MIL-STD/TEMPEST reaccreditation (12-24 months), (c) retraining across all services (12-24 months), and (d) replacement of 100K+ fielded units. The software-defined architecture deepens this lock-in: May 2026 software update turned 100K+ already-fielded Falcon radios into C-UAS sensors without any hardware change — each new capability makes the installed base MORE valuable, not less.

The 10-Q says CSD revenue increased primarily because of higher Mission Critical Communications revenue tied to increased international deliveries for “software-defined resilient communications equipment.” That is the current proof point for the thesis: the installed comms stack is being monetized through software-defined upgrades and international fielding, not commoditized hardware replacement.

The thesis is the tactical SRM bottleneck behind counter-UAS / missile interceptor supply. LHX’s Aerojet assets sit in a constrained U.S. motor base where lead times and qualification cycles are the friction.

Dual bottleneck. (PA) Every US kinetic interceptor — PAC-3 MSE, SM-6, AMRAAM, GMLRS, Coyote Block 3 — requires a tactical SRM from the LHX + Northrop/NGIS duopoly; 18–36 month motor lead times are a documented DoD chokepoint. (DS) The CSD sovereign comms installed base (100K+ fielded Falcon radios) carries an NSA Type 1 + MIL-STD + TEMPEST certification wall that makes rip-and-replace a $5.4–10.9B, 5–9 year project.

The binding constraint is SRM capacity throughput + qualification cycle, not demand. Missile Solutions is growing on production/development volume (+$85M Q2 Propulsion Systems) while the DoD-stated 18–36 month motor lead time has not compressed. Every incremental interceptor — Ukraine restock, C-UAS Coyote Block 3 ramp, missile stockpile rebuild — pulls on a two-supplier motor base with 3–5 year new-design qualification. On the comms side, CSD already monetizes the installed base at 26.9% margin; the constraint there is international fielding velocity, not pricing.

`text

One-time switching cost

= integration/engineering + certification + training/logistics

= $10.0M + $5.0M + $6.5M

= $21.5M

Per-radio switching cost

= $21.5M / 1,000

= $21,500

Switching cost as % of assumed unit price

= $21,500 / $75,000

= 28.7%

`

A new entrant would need to beat L3Harris not just on unit price, but also absorb or overcome roughly $21,500 per radio in non-recurring switching costs. That supports the thesis that L3Harris has materially sticky revenue in its tactical communications and electronic-warfare franchise.

\[

\begin{aligned}

\text{Hardware switching cost} &= 1{,}000 \times 8{,}000 = \$8{,}000{,}000 \\

\text{Training switching cost} &= 16{,}000 \times 50 = \$800{,}000 \\

\text{Integration switching cost} &= \$2{,}500{,}000 \\

\text{Total initial switching cost} &= 8{,}000{,}000 + 800{,}000 + 2{,}500{,}000 = \$11{,}300{,}000

\end{aligned}

\]

Annual sustainment is $600,000. The net present value of staying with the incumbent for 10 years at a 10% discount rate is:

\[

\text{PV sustainment} = 600{,}000 \times \left(\frac{1 - (1 + 0.10)^{-10}}{0.10}\right)

\approx 600{,}000 \times 6.1446

= \$3{,}686{,}760

\]

The initial switching cost of $11.3M is roughly 3.1 times the 10-year PV of sustainment. If the buyer expects to stay with the same radio family for 10 years, switching only makes sense if the new vendor’s lifetime cost is at least $11.3M cheaper or if the incumbent cannot meet capability/security requirements.

If the unit price is $6,000 instead of $8,000, the initial switching cost becomes:

\[

(1{,}000 \times 6{,}000) + 800{,}000 + 2{,}500{,}000 = \$9{,}300{,}000

\]

If the fleet size falls to 500 radios, switching cost falls to $6.8M. This illustrates that incumbent advantage is strongest in larger fleets with high training burden and integration costs, not merely hardware cost.

This calculation is explicitly an illustrative model. The parameters \(P\), \(N\), \(T\), \(L\), \(I\), and sustainment are assumptions and are needs primary source validation if used for any investment decision.
