Poland buys Patriot anti-missile system

Poland yesterday signed a $4.75 billion (3.8-billion-euro) contract to purchase a US-made Patriot anti-missile system, a move that is likely to irk Russia as East-West tensions rise. The Patriot is a mobile air-defence system made by US defence firm Raytheon and designed to intercept tactical ballistic missiles, low-flying cruise missiles and aircraft. The first deliveries are expected in 2022.
