What is the threat in the Strait?

• A. Submarines
• B. Mines
• C. Fast attack craft
• D. Swarm boats

Answer: (B)

In a strait, the most dangerous and decisive hazard is a field of mines. Mines sit hidden in the water and can explode when a ship passes overhead, blocking a narrow channel and causing severe damage with little warning. Because straits are chokepoints where vessels must thread through a confined corridor, even a small mine threat can halt traffic, force diversions, and require costly clearance operations before normal transit resumes. Mines can be laid remotely and remain active for long periods, making them a persistent and strategic threat in this kind of environment.

Submarines, fast attack craft, and swarm boats are real threats, but they rely on close contact, visibility, or direct engagement. The mine threat stands out here because it creates a hidden, enduring risk that disrupts passage through the strait until it’s detected and cleared.
