Here is a detailed overview of some of the top missile and weapons systems of the United States, including their current status, approximate costs, and future development trends. Because the topic is broad and many systems involve classified or semi-classified information, the figures here should be understood as estimates and publicly‐available disclosures, not exact contract or unit cost values.
1. Strategic / Intercontinental and Submarine-Launched Missiles
These are the highest‐tier deterrent weapons, forming part of the strategic “triad” (land-based, submarine-based, air‐launched) and thereby underpinning U.S. nuclear / long-range strike capability.
1.1 LGM‑30 Minuteman III (Land-based ICBM)
- The missile is a U.S. land-based intercontinental ballistic missile (ICBM) in service with the United States Air Force.
- Wikipedia
- +1
- One publicly cited historic unit cost for the earlier versions: ~$7 million each (for earlier Minuteman variant) according to a Wikipedia note.
- Wikipedia
- The system is slated to be replaced by the upcoming LGM‑35 Sentinel (also called “Ground Based Strategic Deterrent” or GBSD) starting around 2030.

- Key Points:
1.2 Trident D5 (Submarine-launched ballistic missile – SLBM)
- The Trident D5 is a submarine-launched ballistic missile used by the U.S. (and U.K.).
- Missile Threat
- +1
- It has a very long range (on the order of ~12,000 km according to some publicly available data).
- Missile Threat
- Cost: While a precise publicly-released unit cost is harder to find in open sources, it’s part of a very high-value strategic missile system.
- Key Points:
- Being submarine-launched, it contributes to the survivable leg of the triad (harder to detect / pre-empt).
- It forms a core part of U.S. nuclear deterrence posture.
1.3 Strategic Cruise / Standoff Missiles (eg. AGM‑86 ALCM)
- The AGM-86 is an air-launched cruise missile developed for strategic roles.
- Wikipedia
- Unit cost (historic) for AGM-86B: ~$1 million (with additional conversion costs for variants).
- Wikipedia
- Key Points:
- It demonstrates the U.S. capability for longer-range standoff strike (launched from bombers).
- As missile defence technologies evolve, maintaining credible standoff capabilities remains vital.
2. Conventional High-Value Cruise and Standoff Missiles
These systems are designed for non-nuclear but high-lethality strike missions (land, sea, possibly anti-ship) and are increasingly important in modern warfare.
2.1 AGM‑158 JASSM (Joint Air-to-Surface Standoff Missile)
- The JASSM family is a U.S. air-launched cruise missile with stealthy / low observability features.
- Wikipedia
- Unit cost (publicly available):
- Key Points:
- This missile allows platforms to strike from standoff distances (i.e., outside the range of many enemy defences).
- The increasing unit cost over time reflects added capabilities (range, stealth, sensors).
- The U.S. and allied forces place increasing emphasis on such missiles given modern air defence, anti-access/area denial (A2/AD) environments.
2.2 BGM‑109 Tomahawk (Tomahawk Cruise Missile)
- The Tomahawk missile is a U.S. long-range subsonic cruise missile (ship or submarine launched) primarily for land‐attack.
- Wikipedia
- Unit cost (public figure) for Block IV (2017): ~$1.87 million; ~$2 million (2022) for Block V.
- Wikipedia
- Key Points:
- It shows how cruise missiles are used for precision long-range strike rather than just nuclear deterrence.
- The export cost for certain variants: example ~$4 million (2023) for export.
- Wikipedia
- A mature system, but modernised versions continue to be fielded and sold internationally.
2.3 Anti-Ballistic / Missile Defence Systems (e.g., Terminal High Altitude Area Defense “THAAD”)
- THAAD is a U.S. Army missile defence system designed to intercept ballistic missiles in their terminal phase (descending towards target).
- Wikipedia
- Unit cost: publicly cited ~US$12.6 million per interceptor missile (FY2017) and ~US$1.25 billion per battery.
- Wikipedia
- Key Points:
- Defensive systems are increasingly important given evolving missile threats (ballistic, hypersonic, cruise).
- The cost per missile/interceptor is orders of magnitude less than some strategic offensive missiles, but the overall system cost is still high given associated sensors, radars, command systems.
- Shows dual nature: offensive missiles (to project power) and defensive missiles (to protect assets) are both central to U.S. strategy.
3. Emerging Trends & Future Directions
The U.S. military and the defence industry are actively investing in next-generation missiles, affordability, mass production, new propulsion, and adapting to evolving threats (hypersonics, swarms, anti-access, space).
3.1 Cost Reduction / Mass Production
- The United States Air Force (USAF) has issued a call for a future anti-air missile program (Counter-Air Missile Program, “CAMP”) with a target cost of less than US$500,000 per missile and an annual production rate of 1,000–3,500 units.
- The War Zone
- This is a significant shift: whereas earlier high-end missiles cost millions (or tens of millions) each, the aim is to produce large quantities of relatively inexpensive interceptors or air-launched missiles to overwhelm enemy defences or swap attritively.
- More broadly, an article points out how the “hidden cost of a missile” narrative shows that firing munitions in current operations already runs into hundreds of millions of dollars.
- War on the Rocks
- Example: A Reuters report (March 2025) said that Lockheed Martin unveiled a new “affordable” cruise missile with a unit cost around US$150,000 and range ~500 miles, designed for mass production (up to 2,500 units annually) in the Indo-Pacific context.

- This indicates a strategic shift: simply having a few ultra-expensive missiles may no longer suffice; the quantity, manufacturing rate, and cost-effectiveness are increasingly important.
3.2 Hypersonic, New Propulsion & Advanced Threats
- The U.S. is facing evolving threats (e.g., hypersonic glide vehicles, advanced cruise missiles, anti-ship missile swarms) and is responding by developing new propulsion systems, air-breathing ramjets, and hypersonic weapons. For example:
- A news article reported a new U.S. missile (solid-fuel integral rocket ramjet, SFIRR) tested by the Navy, described as “game-changing” for its supersonic speed and modern propulsion.
- Defensive systems are also evolving: multi-layered missile defence programs (e.g., one called “Golden Dome”) have been announced. The U.S. announced a concept for a space-based missile defence shield with cost estimates in the hundreds of billions of dollars.
For someone keenly interested in the U.S. missile/weapons sector, here are some take-aways:
- Pay attention to unit cost trends: When costs go down significantly (e.g., < $500k), new operational concepts become possible (mass deployment, large salvoes, deeper inventories).
- Range and speed remain premium attributes, especially as adversaries develop better defences. But these often come with higher cost. The challenge: balance capability with affordability.
- Volume matters: In a future conflict, you may need many missiles, not just a few high-end ones. Hence the “affordable mass” concept is key.
- Defence is as important as offence: The ability to intercept or defend against enemy missiles is becoming ever more critical; hence large budgets for missile defence systems.
- Modernisation will cost: Many systems in U.S. service are decades old; upgrading, replacing, sustaining these systems will drive costs.
- Export and alliance dimension: Missile sales abroad help economies of scale and strategic partnerships, but also complicate cost and deployment planning.
- Watch for emerging technologies: Hypersonics, air-breathing engines, networked weapons, space sensors & interceptors — these will shape the next decade of missile development.
