This missile set is in 1/700 scale. It contains 12x Polaris Nuclear Armed Submarine Launched Ballistic Missiles. Once the missiles are cut from the sprue where they are connected at their base they don't require any further finishing.
According to Wikipedia: "The Polaris missile was a two-stage solid-fuel nuclear-armed submarine-launched ballistic missile (SLBM) built during the Cold War by Lockheed Corporation of California for the United States Navy.
It was designed to be used as part of the Navy's contribution to the United States arsenal of nuclear weapons, replacing the Regulus cruise missile. Known as a Fleet Ballistic Missile (FBM), the Polaris was first launched from the Cape Canaveral, Florida, missile test base on January 7, 1960.
Following the Polaris Sales Agreement in 1963, Polaris missiles were also carried on British Royal Navy submarines between 1968 and the mid-1990s.
Plans to equip the Italian Navy with the missile ended in the mid-60s, after several successful test launches carried out on board the Italian cruiser Giuseppe Garibaldi. Despite the successful launching tests, the US never provided the missiles, due to political convenience. Instead the Italian Government set to develop an indigenous missile, called Alfa, with a successful program, officially halted by Italian Nuclear Non-Proliferation Treaty ratification and failure of the NATO Multilateral Force."
