# Defense Contractor 13Fs: A Reader's Guide to LMT, RTX, NOC, GD

> Lockheed Martin, RTX Corporation, Northrop Grumman, General Dynamics, plus Boeing Defense and L3Harris anchor US defense contractor 13F positioning. Multi-year DoD budget trajectory, geopolitical demand drivers, missile-defense reload cycle, plus emerging space defense drive distinctive institutional patterns.

US defense contractor equities form a distinctive aerospace-defense corner of institutional 13F positioning. Lockheed Martin (LMT), RTX Corporation (RTX, formerly Raytheon Technologies), Northrop Grumman (NOC), General Dynamics (GD), Boeing Defense (within BA), plus L3Harris Technologies (LHX) anchor the cohort. Multi-year DoD budget trajectory, multi-year emerging geopolitical demand drivers (Ukraine, Middle East, Indo-Pacific), missile-defense reload cycle, plus emerging space defense drive distinctive institutional positioning. Reading defense contractor 13F positioning requires understanding the budget framework plus the multi-year programmatic dynamics.The defense contractor business modelDefense contractors operate four primary economic engines:DoD budget trajectory. US Department of Defense budget reached $850B+ for FY2024 with multi-year emerging continued growth (FY2025 enacted $886B). Multi-year emerging programmatic priorities including emerging nuclear modernization (Sentinel ICBM, B-21 Raider, Columbia-class submarines) plus emerging hypersonics plus emerging emerging space defense drive program awards.Geopolitical demand drivers. Multi-year emerging Russia-Ukraine war drives munitions plus emerging emerging air defense demand. Multi-year emerging Middle East conflicts drive emerging air defense plus emerging emerging precision munitions. Multi-year emerging Indo-Pacific posture drives emerging shipbuilding plus emerging emerging long-range strike. Multi-year emerging Foreign Military Sales (FMS) drives international revenue (Lockheed F-35 FMS, RTX Patriot, Northrop Global Hawk).Missile-defense reload cycle. Multi-year emerging munitions reload cycle (Javelin, Stinger, Patriot, HIMARS-launched GMLRS, plus emerging emerging air-launched munitions) drives RTX, Lockheed Missile Systems, plus emerging emerging Northrop missile defense. Multi-year emerging emerging multi-year contract awards plus emerging emerging production rate increases drive multi-year visibility.Space defense emerging. Multi-year emerging Space Force budget growth (FY2024 $29.4B) drives emerging space defense awards. Multi-year emerging Next-Generation Overhead Persistent Infrared (NGOPIR), GPS modernization, plus emerging emerging proliferated low-Earth-orbit (LEO) constellation drive Lockheed, Northrop, L3Harris space business. Multi-year emerging emerging SpaceX competition reshape space launch.Major US defense contractor namesLockheed Martin (LMT)Largest US defense contractor plus emerging F-35 fighter aircraft plus emerging emerging missile defense (THAAD, PAC-3) plus emerging emerging space systems plus emerging emerging Sikorsky helicopters. Multi-year emerging operational scaling plus emerging emerging F-35 sustainment scaling.RTX Corporation (RTX)Diversified Raytheon (missiles, integrated air defense) plus Pratt & Whitney (engines) plus Collins Aerospace (avionics, plus emerging emerging cabin). Multi-year emerging Pratt PW1100G engine recall plus emerging emerging Raytheon scaling plus emerging emerging operational integration.Northrop Grumman (NOC)Diversified Aeronautics (B-21 Raider, B-2) plus Defense Systems plus Mission Systems plus Space Systems. Multi-year emerging B-21 Raider development plus emerging emerging Sentinel ICBM plus emerging emerging space scaling.General Dynamics (GD)Diversified Aerospace (Gulfstream business jets) plus Combat Systems (Abrams, Stryker) plus Marine Systems (Virginia plus Columbia submarines) plus Mission Systems plus IT Services. Multi-year emerging shipbuilding scaling.L3Harris Technologies (LHX)Diversified Communications plus Integrated Mission Systems plus Space plus Airborne Systems. Multi-year emerging Aerojet Rocketdyne acquisition (closed 2023) plus emerging emerging propulsion scaling plus emerging emerging operational integration.How institutional managers position around defense contractorsThree patterns appear across smart-money 13Fs:Pattern 1: Quality-compounder concentrationLMT, NOC, GD-concentrated growth manager positions reflect quality defense compounding plus emerging emerging F-35 plus emerging emerging B-21 plus emerging emerging shipbuilding thesis.Pattern 2: Munitions-reload positioningRTX, LMT-concentrated active manager positions reflect munitions reload cycle thesis.Pattern 3: Space-defense positioningLMT, NOC, LHX-concentrated growth manager positions reflect space defense scaling thesis.How to read defense contractor 13F positioningThree rules apply:Rule 1: Identify program exposurePlatform programs (F-35, B-21, Columbia) vs munitions vs space have distinct dynamics.Rule 2: Watch DoD budget trajectoryMulti-year DoD budget plus programmatic priorities drive operator revenue.Rule 3: Cross-check geopolitical demandMulti-year geopolitical dynamics drive Foreign Military Sales.What defense contractor positioning signalsQuality-compounder conviction. Concentrated LMT, NOC, GD positions signal quality defense thesis.Munitions-reload conviction. Concentrated RTX positions signal munitions reload thesis.Space-defense conviction. Concentrated LHX positions signal space scaling thesis.For real-time tracking of defense contractor 13F activity, see the institutional signals feed.

## FAQ

### What are the major US defense contractors?

Six major US defense contractors: (1) Lockheed Martin (LMT) — largest US defense contractor; (2) RTX Corporation (RTX) — Raytheon plus Pratt & Whitney plus Collins; (3) Northrop Grumman (NOC) — B-21 plus Sentinel plus space; (4) General Dynamics (GD) — Gulfstream plus Combat Systems plus shipbuilding; (5) Boeing Defense (within BA); (6) L3Harris Technologies (LHX). Plus Huntington Ingalls Industries (HII).

### How does the DoD budget trajectory work?

US DoD budget reached $850B+ for FY2024 with FY2025 enacted at $886B. Multi-year emerging programmatic priorities including nuclear modernization (Sentinel ICBM $130B program, B-21 Raider, Columbia-class submarines $130B program) plus emerging hypersonics plus emerging emerging space defense drive program awards. Multi-year emerging defense spending share of GDP (3.0-3.5% range) drives baseline trajectory.

### What is the munitions reload cycle?

Multi-year munitions reload cycle drives RTX, Lockheed Missile Systems plus emerging emerging Northrop missile defense revenue. Munitions including Javelin (RTX-Lockheed JV), Stinger (RTX), Patriot (RTX), HIMARS GMLRS (Lockheed), plus emerging air-launched munitions (AMRAAM, JASSM, LRASM). Multi-year multi-year contract awards plus production rate increases drive multi-year visibility. Reading munitions production rate drives institutional positioning.

### How do Foreign Military Sales drive defense revenue?

Foreign Military Sales (FMS) drive international defense revenue. Major FMS programs include Lockheed F-35 (sold to UK, Israel, Japan, Korea, Australia, Italy, Netherlands, Norway, Denmark, Belgium, Finland, Switzerland, Germany, Romania, Czech Republic, Greece, plus emerging emerging), RTX Patriot (Poland, Sweden, Germany, Romania, emerging), Northrop Global Hawk plus E-2D. Multi-year emerging FMS plus emerging Direct Commercial Sales (DCS) drive international revenue.

### What is the B-21 Raider program?

Northrop Grumman B-21 Raider stealth bomber program targets emerging operational deployment plus emerging emerging total fleet of 100+ aircraft replacing aging B-1 plus B-2. Multi-year emerging program execution plus emerging emerging fixed-price low-rate initial production losses (LRIP1-5) plus emerging emerging full-rate production transition drive multi-year operational trajectory. Multi-year emerging emerging B-21 ramp drives Northrop institutional positioning.

### What signals defense contractor cycle inflections?

Four signals: (1) DoD budget enactment plus emerging emerging Continuing Resolution dynamics; (2) major program milestones (F-35 sustainment, B-21 LRIP, Columbia keel laying); (3) munitions reload contract awards; (4) Foreign Military Sales authorizations. Concentrated 13F changes around these signals reveal manager cycle reading.
