China Coast Guard New 10,000T + ship H/PJ26 stealthy 76 mm dual purpose gun mount, which is a Chinese development of Russian AK-176. The adoption of smaller caliber gun is the result of the need of higher rate of fire for air defense, including sea-skimming anti-ship missiles. H/PJ26 utilizes advanced synthetic material such as fiber glass to a much greater degree than the original AK-176, resulting in over 30% of weight reduction to 11.5 ton of H/PJ26, as opposed to the 16.8+ tons of AK-176.
