Most Strategic Security Blog readers are probably already aware of the recent outbreak of Foot and Mouth Disease (FMD) in the UK, but I thought it might be useful to post summary information on what we know to date. In short, it appears as if the virus was found on two farms, that the likely source of the virus was a research and vaccine production facility located nearby, and that there will be hell to pay if it is determined that someone at that facility is responsible for the outbreak and subsequent shut down of beef exports from the UK. The good news is that the response to this outbreak was vastly improved from a 2001 outbreak, which resulted in close to 7 million animals being destroyed. The bad news is that it was probably released from a laboratory and will no doubt spark new concerns about animal disease research.

Details:
An out break of FMD was confirmed on August 3rd on a farm in Surrey, according to the British Department for Environment Food and Rural Affairs (DEFRA). A second case was found at a nearby farm, but tests at two other farms were negative. The owner of the Woolford Farm, where the first disease outbreak was found, reported symptoms to his veterinarian and then DEFRA on the 2nd. DEFRA said in a statement that the strain is a 01 BFS67-like virus, isolated in the 1967 FMD outbreak in the UK. That strain was being used this past July for vaccine production at a nearby facility run by Merial Animal Health, which is jointly owned by Merck and French pharmaceutical company Sanofi-Aventis.

“It is not true,” British Defence Secretary Des Browne insisted during an interview with BBC radio, that a new fuze planned for British nuclear warheads and reported by the Guardian will increase their military capability. The plan to replace the fuze “was reported to the [Parliament’s] Select Committee in 2005 and is not an upgrading of the system; it is merely making sure that the system works to its maximum efficiency,” Mr. Browne says.

The minister is either being ignorant or economical with the truth. According to numerous statements made by US officials over the past decade, the very purpose of replacing the fuze is – in stark contrast to Mr. Browne’s assurance – to give the weapon improved military capabilities it did not have before.

The matter, which is controversial now because Britain is debating whether to build a new generation of nuclear-armed submarines, concerns the Mk4 reentry vehicle on Trident D5 missiles deployed on British (and US) ballistic missile submarines. The cone-shaped Mk4 contains the nuclear explosive package itself and is designed to protect it from the fierce heat created during reentry of the Earth’s atmosphere toward the target. A small fuze at the tip of the Mk4 measures the altitude and detonates the explosive package at the right “height of burst” to create the maximum pressure to ensure destruction of the target. The new fuze will increase the “maximum efficiency” significantly and give the British Trident submarines hard target kill capability for the first time.

British Vanguard-class ballistic missile submarines have at least 15 years more service life in them, and the U.K. government does not have to make a decision now on whether to replace them with a new class of submarines, Richard Garwin told BBC radio Tuesday.

Garwin, who is a member of the Federation of American Scientists Board of Directors and a long-term adviser to the U.S. government on defense matters, is in Britain to testify before the House of Commons Defence Select Committee on the future of Britain’s nuclear deterrent.

The U.K. government announced on December 4, 2006, that it had decided to replace its current Vanguard-class sea-launched ballistic missile submarines (SSBNs) with a new class to enter operation in 2024. If approved by the parliament, the plan would extend Britain’s nuclear era into the 2050s.

According to the U.K. government, a decision to build a new new class must be made now because the Vanguard-class SSBNs only have a have a design life of 25 years. But Garwin says that the submarines have a minimum design life of 25 years, which can be extended by at least another 15 years. A decision made now is premature and unwise, Garwin told BBC, because the large Trident missiles may not be necessary 15 years from now.

North Korea may have gotten all the attention, but all the nuclear weapon states were busy flight-testing ballistic missiles for their nuclear weapons during 2006. According to a preliminary count, eight countries launched more than 28 ballistic missiles of 23 types in 26 different events.

Unlike the failed North Korean Taepo Dong 2 launch, most other ballistic missile tests were successful. Russia and India also experienced missile failures, but the United States demonstrated a very reliable capability including the 117th consecutive successful launch of the Trident II D5 sea-launched ballistic missile.

The busy ballistic missile flight testing represents yet another double standard in international security, and suggests that initiatives are needed to limit not only proliferating countries from developing ballistic missiles but also find ways to curtail the programs of the existing nuclear powers.

After having spent the last several years sending diplomats to Teheran to try to persuade Iran not to develop nuclear weapons, the British government announced Monday that it plans to renew its own nuclear arsenal.

If approved by the parliament, Monday’s decision means that the United Kingdom will extend its nuclear deterrent beyond 2050, essentially doubling the timeline of its own nuclear era.

Doing so is entirely consistent with the United Kingdom’s international obligations under the Non-Proliferation Treaty (NPT) and with a policy that favors complete elimination of nuclear weapons, the government insisted in a fact sheet, because the British nuclear arsenal today is smaller than during the Cold War, and because the Treaty does not say exactly when nuclear disarmament has to be accomplished. In fact, the new plan has “the right balance,” the government claims, between working for a world free of nuclear weapons and keeping those weapons.

Although the British government has promised a full and open public debate about the future of Britain’s nuclear deterrent, it has so far failed to explain what decisions need to be made, failed to provide a timetable for those decisions, and has refused to participate in a House of Commons Defence Committee inquiry on the future of Britain’s nuclear deterrent, according to a British parliamentary report. The report partially relies on research conducted by the FAS Nuclear Information Project for the SIPRI Yearbook.
