It took less than six minutes for Japan’s Type 88 missile to find its mark, a decommissioned Philippine warship 75km (47 miles) off the coast of Ilocos Norte. The US-made Tomahawk took rather longer to hit its target, some 630km (390 miles) away. It was, analysts say, a pointed display of resolve: Japanese, American and Filipino troops bringing this year’s Balikatan joint exercises to a thunderous close with a volley of missiles fired from sites in the far northern Philippines.
