Removing the political bits ---------------- (Reuters) - Iran unveiled on Tuesday what it said was an upgraded short-range missile and said it would build a new air defense site, in what appeared to be an attempt to show its readiness against any Israeli attack. President Mahmoud Ahmadinejad and Defence Minister Ahmad Vahidi attended a ceremony at which officials unveiled the fourth-generation Fateh 110 short-range missile, with a range of about 300 km (180 miles), and other upgraded hardware. ..... ..... Separately, Iran announced the start of construction on an air defence site, to be built in the south of the country about 210 km (130 miles) from its uranium enrichment facility in Isfahan, officials said. The 200-hectare air defence installation in the Abadeh area would be the largest in that part of the country and will be built by Khatam al-Anbia, the engineering arm of Iran's Islamic Revolutionary Guard Corps, and will eventually employ 6,000 people, Fars reported. ...... ...... Iran said earlier this month that it had successfully test-fired the new Fateh-110 model and that it was equipped with a more accurate guidance system. "This missile is one of the most precise and advanced land-to-land ballistic missiles using solid fuel," Vahidi was quoted as saying by Fars. In July, Iran said it had successfully test-fired medium-range missiles capable of hitting Israel, and tested dozens of missiles aimed at simulated air bases. It also presented a more powerful, 5,000-horsepower sea-borne engine, the Bonyan-4, Fars quoted Vahidi as saying. A previous version had 1,000 horsepower, the Iranian Students' News Agency (ISNA) said. Military experts have cast doubt on Iran's claims of weapons advances, especially its assertions about its missile program, saying Tehran often exaggerates its capabilities. "The Fateh-110 has a crude guidance and control system that operates during the missile's ascent" rather than during final descent, said Michael Elleman, senior fellow for missile defence at the International Institute for Strategic Studies. "The Fateh-110 appears to lack the subsystems needed to effect terminal steering," he said in an email. Iran on Tuesday also presented Armita, an "airborne laboratory" to help test aircraft launch systems and oxygen generation and train fighter pilots, Fars reported. Vahidi said it was named after the daughter of Dariush Rezaeinejad, an Iranian scientist who was shot dead last year. Iran believes agents working with foreign intelligence services including the American CIA and Israel's Mossad are behind the assassinations of several of its nuclear scientists.
