USNI News – Japan still lacks a key element of military power relevant for emerging challenges in the region—a flexible, long range strike weapon. The Tomahawk missile has long been a centerpiece of the U.S. military’s long-range precision strike portfolio. A sea-based weapon with a 1,000-mile range and a 1,000-pound warhead, it brings a proven proficiency for attacking well-defended, high-value land targets. New upgrades, including the ability to hit a ship, ensure the missile’s operational relevance beyond the next decade. The precedent for providing Tomahawk to allies was established nearly 20 years ago when the United Kingdom acquired 65 missiles. It is time to expand the “user club” to include Japan.
