Asia’s spending on military hardware is quickening at a time of increasing focus over maritime territorial disputes in the South and East China Seas, as well as growing concern over China’s expanding military.

Earlier this year London-based Strategic Defense Intelligence (DSI) reported that Asia led the world in rising defense spending, and countries’ spending on submarines was at the top of the list.

DSI analysts say the Asian submarine market is currently worth just over $7 billion, but will rise to $11 billion by 2025. That could mean it surpasses Europe as the world’s second largest submarine market, behind the United States.

… Collin Koh, an associate research fellow at Singapore’s S. Rajaratnam School of International Studies (RSIS), said the buildup of submarines is geared “to provide a weapon for the weak against the strong.”

Koh told VOA that submarines “do constitute one of the major focus areas of capability build up.” Submarines entering service “in the near future will be larger than those used to be operated in the region, and of course, better armed and equipped.”

But Koh said then navies need to overcome several challenges including financial, technical, logistics and manpower issues of submarine operations.

“Not all of these countries that purchase submarines necessarily master the art of underwater warfare,” he said.
