Islamabad:  Pakistan is preparing to launch its first Chinese-built submarine in 2026 as part of a $5 billion defence agreement with China, marking a major step in strengthening its naval power and strategic partnership with Beijing.

The deal, which includes eight Hangor-class diesel-electric submarines, was signed between Pakistan and China in 2015. According to officials, the first four submarines are being built in China, while the remaining four will be assembled in Pakistan to enhance local shipbuilding and technical capabilities.

Pakistan’s naval chief, Admiral Naveed Ashraf, confirmed that the submarine project is progressing smoothly and that the new fleet will significantly boost Pakistan’s ability to protect its maritime interests in the Arabian Sea and the Indian Ocean.

The Hangor-class submarines, based on China’s advanced Type 039A design, are expected to feature modern stealth technology and advanced weapon systems. These submarines will replace Pakistan’s ageing fleet and expand its underwater defence capabilities.

China’s shipbuilding corporation has already completed two submarines for Pakistan, and the third one was handed over earlier this year. The remaining units are under various stages of construction, with deliveries expected to continue until 2028.

Defence experts say the submarine deal highlights the deepening military cooperation between China and Pakistan. It also strengthens the China-Pakistan Economic Corridor by improving maritime security in the region.

The new submarines are expected to enhance Pakistan’s deterrence capabilities and improve its surveillance and operational reach across key maritime zones. However, regional observers note that the move may heighten tensions with India, which has been closely monitoring Pakistan’s growing naval ties with China.

With the launch of the first submarine planned for 2026, Pakistan’s navy is aiming to enter a new era of modern underwater warfare and regional maritime security.
