Thailand and China have signed a contract on the delivery of the first of three submarines that Thailand’s naval forces plan to purchase from Beijing over the course of the next 11 years, media reported Friday.

BANGKOK (Sputnik) — According to the Bangkok Post newspaper, the representatives of the Royal Thai Navy and Chinese state enterprise China Shipbuilding & Offshore International Co (CSOC) signed the document in Beijing. China introduced no changes to the version of the contract, which was edited by the Thai attorney-general, the daily added.

Under the contract, Thailand will buy three Yuan Class S26T submarines worth a total of around 36 billion baht ($1 billion), with 700 million baht ($20.2 million) due to be paid within 45 days. The first submarine is expected to be delivered within six years. China also agreed to provide CM-708 missiles, which can be fired from the submarine over a range of 290 kilometers (180 miles), free of charge.

On April 18, Thailand’s cabinet of ministers approved, in secrecy, the decision to acquire a 13.5 billion baht ($390 million) submarine from China and two more over the next 11 years. As a result, a large number of activists, politicians and members of society raised concerns over the impact of the submarine purchases on the national economy and defense budget, as the deal may deprive the country of its military budget in case of emergencies, while the expediency of the submarines in general were also questioned. On April 28, local media reported that Thailand’s Office of the Auditor-General (OAG) decided to launch a probe into the Royal Thai Navy’s plans to purchase three submarines from China due to the strong criticism which came after the deal was struck upon the petition of one of the activists.

The new missile, dubbed the CM-708 UNB, is purportedly a derivative of a longer-range version of the submarine-borne YJ-82 ASCM, a rocket-propelled missile launched in a buoyant capsule, with an estimated range of 30 to 40 kilometers (18–24 miles).

The CM-708 UNB, produced by the China Aerospace Science and Industry Corporation (CASIC), allegedly has a range of about 290 kilometers (180 miles) — more than twice the range of a similar ASCM revealed in 2014, the so-called CM-708 UNA, which has a range of 128 kilometers (79 miles).

IHS Jane’s Defense Weekly outlines additional technical specifications of the new weapon:

A 1,200 kg ‘torpedo’ carrier launches the 5.05 m and 700 kg missile, which has a speed of Ma .08 to Ma .09 and uses integrated INS/Satellite and millimeter wave radar for guidance. It is armed with a 155 kg warhead and in its terminal phase flies 5-7 m above the water.

Like the CM-708 UNA, the CM-708 UNB is likely designed to target medium-to-large vessels and could pose a danger to U.S. carrier strike groups. “The CM-708, encased in a torpedo like case, is shot out from the submarine’s torpedo tube, through the water and into the air. The missile then breaks free of its casing, fires its booster and then engine, and flies out to hit its target ship,” Popular Science explains when describing the 128 kilometer variant of the ASCM in 2014.

If the new ASCM’s range proves accurate, it would put Chinese submarines at a safe distance from most anti-submarine warfare systems.  The domestic version of the missile is (or will) likely be deployed aboard China’s conventional submarine fleet, which consists of 13 Song-class (Type 039) diesel-electric attack submarines and 13 more advanced Yuan-class (Type 039A) submarines equipped with air-independent propulsion (AIP) systems.

China Aerospace Science and Industry Corporation (CASC) is offering the submarine-launched CM-708UNB Sea Eagle ASM. It provides not just People’s Liberation Army Navy (PLAN) submarines, but now foreign buyers, with a stealthy capability to strike naval vessels and inshore targets within a 290km range.

The Sea Eagle has a launch depth of 60m within a 528mm launch tube. Source
