This is a resin and white metal ship model kit.
Yankee Modelworks of the US is a maker of fine full resin kits, resin conversion kits, resin detail sets, and photo-etched metal detail sets.
The USS Simon Bolivar was part of the Benjamin Franklin class of Fleet Ballistic Missile Submarines built during the 1960s. During her 30 years of service, the Simon Bolivar alternated with other SSBNs in keeping the fleet ballistic missile submarines on deterrent patrols, providing the United States with instant retaliatory capabilities in case of attack.
This kit of the USS Simon Bolivar measures 14.57 inches (36.83cm) long and is a perfect first kit. The hull is a single casting with metal dive planes and comes complete with resin, white metal, and photo-etch parts. A great weekend project.
