The U.S. Air Force has demonstrated a new way to use the B-2 Spirit for maritime strike by pairing the stealth bomber with QUICKSINK, a low-cost, JDAM-derived weapon adapted from a gravity bomb originally designed for land targets. Recent Air Force reporting and testing has included a 500-pound QUICKSINK drop at Eglin Air Force Base’s Gulf Test Range and a Sept. 3, 2025, U.S.-Norway maritime strike demonstration in the Norwegian Sea that aimed to “engage and sink the maritime target.” Together, the events highlight an effort to add a cheaper anti-ship option alongside more expensive, purpose-built missiles.
From Land Bomb to Ship Killer
QUICKSINK works by retrofitting a standard JDAM, one of the most common precision-guided bombs in the U.S. inventory, with a seeker and guidance package that lets it track and strike moving ships. The Air Force Research Laboratory developed the concept to give bomb-carrying aircraft an anti-ship option that is generally cheaper than dedicated missiles like the Long Range Anti-Ship Missile. The smaller variant tested recently is based on the 500-pound GBU-38, a weapon already produced in large quantities and stockpiled across the force.
That production base matters. In a prolonged conflict, the ability to convert existing bomb stocks into ship-killing weapons could offset the limited inventories of specialized anti-ship missiles. JDAM kits are widely described as far cheaper than dedicated anti-ship missiles such as Harpoon. The QUICKSINK modification adds targeting hardware to that cheap airframe, creating a weapon that can be scaled quickly through existing supply chains rather than purpose-built production lines. For a military that worries openly about running out of precision munitions in a major war, that arithmetic changes the calculus of naval strike planning.
B-2 Proves the Concept at Eglin
The Air Force confirmed that a B-2 Spirit delivered a 500-pound QUICKSINK variant during a test at Eglin Air Force Base’s Gulf Test Range. The bomber successfully engaged a surrogate maritime target, demonstrating the weapon’s integration and performance in a controlled test setting from a stealth platform. The test built on an earlier successful demonstration using a larger 2,000-pound variant, which proved the core concept of turning a gravity bomb into a guided anti-ship weapon.
Scaling down from 2,000 pounds to 500 pounds is not a minor detail. The smaller bomb means a single B-2, depending on loadout, could potentially carry more weapons and engage multiple targets on a single sortie rather than expending its payload on just a few. That shift in magazine depth changes the threat equation for any adversary trying to defend a surface fleet. A stealth bomber that can approach undetected and release a salvo of cheap, guided anti-ship bombs presents a problem that traditional naval air defenses were not designed to solve. In general, many shipboard defenses are designed with cruise-missile threats in mind, and a volley of small guided bombs arriving from above could present a different engagement problem.
Norwegian Sea Test Adds Allied Dimension
U.S. and Norwegian forces also conducted a long-range maritime strike demonstration in the Norwegian Sea on Sept. 3, 2025, with the stated objective to “engage and sink the maritime target.” A B-2 took part in the event, and Norwegian F-35s provided allied participation and support, adding a coalition dimension that goes beyond a simple range test.
The choice of location carries its own message. The Norwegian Sea sits along the northern flank of NATO, a region where Russian naval activity has increased in recent years and where allied forces practice defending critical sea lanes connecting North America to Europe. Running a QUICKSINK exercise there, with a Norwegian partner already flying the F-35, suggests the U.S. and its allies are thinking about how to distribute anti-ship strike capability across multiple platforms and nations. If the JDAM-based weapon proves reliable enough for operational fielding, any allied aircraft capable of dropping a GBU-38 could theoretically carry a QUICKSINK variant, spreading the ship-killing role far beyond dedicated naval strike squadrons.
Why Stealth Changes the Anti-Ship Equation
Most coverage of QUICKSINK has focused on its low cost, but the pairing with the B-2 deserves closer scrutiny. A gravity bomb, even a guided one, has a much shorter range than a cruise missile. That means the launching aircraft must get relatively close to the target ship, which is normally a death sentence against a modern navy equipped with long-range surface-to-air missiles and advanced radar. The B-2’s stealth profile changes that risk calculation. Its low-observable design allows it to penetrate defended airspace and reach weapon release points that would be inaccessible to conventional bombers or fighter aircraft carrying the same munition.
This creates an asymmetric cost problem for adversaries. Defending a fleet against stealth bombers armed with cheap guided bombs requires expensive, high-end air defense systems running continuously. Each interceptor missile fired at an incoming QUICKSINK round costs far more than the weapon it is trying to destroy. Over time, that exchange rate favors the attacker, especially if the bomber can release multiple weapons per pass and return for additional sorties. The strategic logic mirrors the broader Pentagon push toward affordable, mass-producible weapons that can overwhelm defenses through volume rather than individual capability.
What Remains Unproven
For all the promise, significant questions remain. The Air Force has not released accuracy metrics, hit probability data, or detailed sensor performance figures from either the Eglin test or the Norwegian Sea demonstration. Success against a stationary or slowly moving surrogate target on a test range does not guarantee effectiveness against a maneuvering warship deploying electronic countermeasures and decoys. Modern surface combatants can change course and speed rapidly, employ jamming and spoofing techniques, and coordinate layered defenses with other ships and aircraft. How QUICKSINK’s seeker performs in that contested environment is still unknown outside classified channels.
There are also operational questions about targeting and cueing. A stealth bomber may be able to get close enough to drop the weapon, but it still needs accurate, timely data on where a ship is and where it is heading. Maritime targeting has historically been a weak point for long-range airpower, often relying on a network of satellites, patrol aircraft, submarines, and surface ships to find and track adversary vessels. Integrating QUICKSINK into that broader kill chain will determine whether it becomes a niche capability for controlled exercises or a routinely available option for combatant commanders. Until the Air Force demonstrates the weapon in more demanding scenarios and shares at least some performance data, QUICKSINK will remain a promising but still partially unproven answer to the challenge of sinking ships on the cheap.
