Navy Drill of Iran Velayat 97

Iran will hold a three-day navy drill Velayat 97 in a vast area of the Gulf and the Indian Ocean including a sensitive global shipping route.

Features of the Velayat 97

  • The three-day navy drill would be held in the waters of Strait of Hormuz, Makran coast, Oman Sea and the north of the Indian Ocean, covering 2 million square kilometres.
  • The navy drill Velayat 97 aims to evaluate the navy’s equipment, practice launching weapons and enable the troops to gain readiness for a real battle.
  • The three-day drill will showcase Iran’s submarines, warships, helicopters and drones, according to the admiral.
  • The drill also includes missile launches from the vessels.

Will Velayat 97 further heighten the tensions?

The Strait of Hormuz is a vital international transit route. American forces routinely pass this route and it has earlier witnessed some tense encounters between American and Iranian forces.

Iran’s show of military might through Velayat 97 comes at a time of heightened tensions with Iran’s main regional rival Saudi Arabia and with the United States of America which last year withdrew from the 2015 nuclear deal with Iran and reimposed sanctions on the Islamic Republic.

China develops underwater surveillance networks in Indian Ocean, South China Sea

China has successfully developed new underwater surveillance network to help its submarines get stronger lock on targets while protecting nation’s interests along maritime Silk Road, which also includes Indian Ocean. The project is part of unprecedented military expansion fuelled by China’s desire to challenge United States in world’s oceans.

Underwater surveillance network

The network is underwater surveillance system based on network of platforms — buoys, satellites, surface vessels and underwater gliders — that gather data from Western Pacific, South China Sea and Indian Oceans. The system works by gathering information about underwater environment, particularly water temperature and salinity, which navy can then use to more accurately track target vessels as well as improve navigation and positioning. The new surveillance system will enable Chinese submarines to steer a much safer course through difficult waters as well as improving their targeting ability.
