The Evolving Threat Landscape: Lessons from the Red Sea Conflict
The recent combat operations in the Red Sea have provided invaluable insights into the evolving threat landscape and the preparedness of the U.S. Navy. From October 2023 to January 2025, the Navy engaged in the most intensive naval combat since World War II, utilizing an unprecedented number of munitions. This period of intense military activity has revealed critical gaps in naval defense and highlighted the need for strategic changes in the Navy’s weapons production and deployment.
Naval Combat in the Red Sea: A New Era of Warfare
The U.S. Navy’s engagement in the Red Sea began shortly after the Hamas attack on Israel, escalating into an undeclared shooting war with Houthi rebels in Yemen. The destroyer USS Carney faced its first major combat test on October 19, 2023, shooting down 15 Houthi drones and four cruise missiles over a span of 10 hours. This intense engagement marked the beginning of a prolonged conflict where the Navy’s tactics and resources were put to the ultimate test.
The High Cost of Naval Defense
Retired Navy Cmdr. Bryan Clark of the Hudson Institute noted that the U.S. Navy has expended more missiles for air defense in the Red Sea conflict than in all the years since Operation Desert Storm in the 1990s. Estimates suggest that the Navy has used over $1 billion worth of interceptors to counter drone and missile threats. This depletion has left the Navy in a precarious position. If the United States and China were to engage in conflict today, the Navy would likely run out of weapons in a matter of days.
The Weapons Supply Challenge
The current issue lies in the specialized nature of modern U.S. Navy weapons. These munitions are highly specialized, often manufactured by hand, and depend on low-rate production. The bespoke supply chain and high production costs of these unique weapon systems pose significant challenges to rapid replenishment.
Transitioning to Alternative Tactics
Given the high cost and limited supply of missiles, the Navy has begun transitioning to less-expensive solutions. In January, it was reported that the Navy fired 160 rounds from five-inch main guns, utilizing Hypervelocity Projectiles originally developed for the railgun program. The USS Rafael Peralta, shown in action in June 2023, exemplifies this shift. These projectiles are designed to hit targets directly, making them effective against low-flying drones that miss the minimum engagement range of missiles [We dont need the reference here].
“These cost-effective measures not only diversify our response to threats but also preserve our high-value munitions for scenarios where they are indispensable,” said naval analysts observing the transition.
Reprioritizing Naval Defense
The Red Sea conflict has exposed a dangerously low level of stockpiled weapons. John Phelan discussed this issue during his Navy secretary confirmation hearing, noting the (suspect)- subgroup need to prioritize resupplying and replenishing the navy’s stockpile. More innovatively, the proposed defense strategies will bolster the Navy’s defenses through a blend of guns, directed energy, and loitering munitions.
“For the future of naval warfare, diversification in tactics and staying versatile with our strategy is key. Incorporating directed energy weapons and leveraging loitering munitions can also complement traditional naval defenses.” Bryan Clark expressed.

Table: Navy Munitions Utilized in the Red Sea
| Munitions Used | Total Fired | Cost Per Unit |
|---|---|---|
| SM-2 Missiles | 120 | $2.5 million |
| SM-6 Missiles | 80 | $4.3 million |
| SM-3/ESSM Missiles | 20 | $12.5-$28.7 million |
| Sidewinder Missiles | N/A | $0.5 million |
| Hellfire Missiles | N/A | $0.15 million |
Navigating the Future of Naval Defense
Navigating the future landscape of naval defense will focus on the integration of directed energy and loitering munitions to fill gaps left by the high cost of missiles. These new technologies are often less specialized and can be produced at a faster rate, ensuring that the Navy is better prepared for future conflicts.
Innovations on the Horizon
The utilization of 5-inch Hypervelocity Projectiles and the shifting landscape of drone engagements have shown promising potential for future innovations. Reports note the developmental progress of rail gun technology and guided conventional weapons can bridge the gap between missile deployment and effective, cost-efficient naval defense. With these advancements, the Navy can ensure operational readiness and flexibility.
Finally, said Rear Admiral Hakimzadeh, "This new theater of warfare calls for bold new strategic initiatives…. these emerging capabilities."

FAQ Section
Q: How has the Red Sea conflict impacted the U.S. Navy’s arsenal?
The conflict in the Red Sea has significantly depleted the U.S. Navy’s missile stockpile, with estimates suggesting the Navy has used over $1 billion worth of interceptors. This has highlighted the need for more cost-effective and rapidly producible weapon systems.
Q: What are some alternatives to traditional naval missiles?
Alternatives include five-inch main guns using Hypervelocity Projectiles, directed energy weapons, and loitering munitions. These solutions are less expensive and can be produced more quickly than specialized missiles.
