History:
The 747-100 was the original variant launched in 1966. The 747-200 soon followed, with an order in 1968. The 747-300 was launched in 1980 and was followed in 1985 by the 747-400. Lastly, the 747-8 was announced in 2005. Several versions of each variant have been produced. Many of the early variants were in production simultaneously.
The first 747-100s were built with six upper-deck windows (three per side) to accommodate upstairs lounge areas. Later, as airlines began to use the upper-deck for premium passenger seating instead of lounge space, Boeing offered a 10-window upper deck as an option. Some -100s were retrofitted with the new configuration. The -100 was equipped with Pratt & Whitney JT9D-3A engines. No freighter version of this model was developed by Boeing. However, 747-100s have been converted to freighters. A total of 167 747-100s were built.
