That's why you need to eliminate the old VLS. 9B will be exclusive to the U-VLS and requires an upgraded Type 346. PLAN will not continue to produce 9A for the sheer benefit of only 6 ships, no sirree. Ditto with the YJ-62 which only six ships use.I don't like the idea to mix different types of VLS together, calling for logistics troubles. It shouldn't be too difficult to port the 9B to the old VLS.
