Background
From March 2014 HMS Tireless Mystery :

"Making news today, it has just been revealed that a Briritsh SSN, HMS Tireless (S88), was refused entry to the United Arab Emirates.  The Royal Navy downplayed the refusal, hinting that it amounted only to a "delay" rather than a safety issue. Curiously, UAE authorities have not commented."

A week after the vessel had first been refused clearance, the Royal Navy finally decided to dock at Goa, India.

 "We do not discuss submarine movements for reasons of security." - The Royal Navy

"A small number of families did travel to the region at their own expense in anticipation of the visit. They were kept informed of the situation by local Royal Navy personnel ashore." 

 The Foreign and Commonwealth Office denied there were any diplomatic issues between the UK and the UAE.
Was the port denial a cover story to explain a detour to the Indian Oean for a secretive intelligence gathering mission by the British SSN Tireless? 


Synthesis 

• [T]he Indian media reported that a type-093 attack nuclear submarine was on deployment (December 2013 to February 2014) in the Indian Ocean and that the Chinese Ministry of National Defense (Foreign Affairs Office) had informed the Indian military attaché in Beijing of the submarine deployment to show ‘respect for India’. Apparently, the information of the deployment was also shared with the United States, Singapore, Indonesia, Pakistan and Russia.
• On 1 April 2014, Tireless arrived in the southern Indian Ocean to join the search for a missing Malaysian airliner, where its sophisticated underwater listening equipment was used in an unsuccessful to attempt to detect the underwater locator beacon of the aircraft's flight recorders. 
• China had deployed a number of ships, aircraft and satellite in the southern Indian Ocean in its attempt to locate the debris of MH 370. These factors may have encouraged the Chinese Navy to dispatch the submarine to the Indian Ocean.

Tireless had been scheduled for retirement during 2013, but its service was extended until eventual decommissioning on 19 June 2014.

Had China deployed an SSN to the Indian Ocean as speculated above, some rather nice technical data about it could have been discretely collected by a properly equipped HMS Tireless. 

On 1 April 2014, Tireless arrived in the southern Indian Ocean to join the search for a missing Malaysian airliner, where its sophisticated underwater listening equipment was used in an unsuccessful to attempt to detect the underwater locator beacon of the aircraft's flight recorders.  On 1 June 2014 Tireless returned to Plymouth for the last time before decommissioning, and was formally decommissioned on 19 June.

What was Tireless's secretive mission?  Who injected the bogus MH370 locator signals. Was the Chinese submarine responsible for the little-mentioned MH370 encrypted chirping as a warning to the U.S. that their technology has already been hacked?  

Tireless will be replaced on active duty by HMS Artful^,[5][4]  which only completed its maiden dive recently.

Submarines are always silent and strange.
