"LONDON, Nov 23 (Reuters) - The U.S. military has stepped up chartering of tankers and requests for extra fuel in the U.S. Central Command area, which includes the Gulf, shipping and oil industry sources say. A Gulf oil industry source said the charters suggested there would be high naval activity, possibly including a demonstration to Iran that the U.S. Navy will protect the Strait of Hormuz oil shipping route during tensions over Tehran's nuclear programme.
The U.S. Navy's Military Sealift Command (MSC) has tendered for four tankers in November to move at least one million barrels of jet and ship fuel between Gulf ports, from Asia to the Gulf and to the Diego Garcia base, tenders seen by Reuters show. It usually tenders for one or two tankers a month to supply Gulf operations, which include missions in Iraq."
A separate requirement is for a tanker to move 147,000 barrels of ship fuel from Singapore to Diego Garcia in the Indian Ocean, close to the Gulf and Arabian Sea.
As Larissa notes:
that is indeed unusual according to a military friend of mine, who in an email this morning wrote: "It has gotten my attention. I don't have an explanation."
The US is secretly upgrading special stealth bomber hangars on the British island protectorate of Diego Garcia in the Indian Ocean in preparation for strikes on Iran’s nuclear facilities, according to military sources. The improvement of the B1 Spirit jet infrastructure coincides with an “urgent operational need” request for £44m to fit racks to the long-range aircraft. That would allow them to carry experimental 15-ton Massive Ordnance Penetrator (MOP) bombs designed to smash underground bunkers buried as much as 200ft beneath the surface through reinforced concrete.
