Eyeing China, the Philippines wants to buy its first attack submarine

• The Philippines wants to buy its first submarine as tensions in the region mount.
• Experts say their money would be better spent on drones and missile boats.
• There are powerful symbolic reasons for the Philippines to join the sub club.

Amid rising tensions with China, the Philippines is planning to buy its first submarine.

The Philippine government says this reflects a shift from internal counterinsurgency against rebels to external defense of the nation's sovereignty as China's military power grows in the South China Sea. But some experts question whether buying a sub makes sense given more cost-effective weapons to counter China, or whether it will even happen.
