MIAMI – Today in Aviation, the launch of the Boeing 777-300 aircraft took place in 1995 when the company announced the type at the Paris Air Show.

The triple seven 300 series had to wait two more years to take to the skies and prove to be larger in range and passenger capacity than its predecessor, the Boeing 777-200, with its almost 1000 nautical miles and 50 more seats.

The Boeing 777 Program


Having been in the manufacturing market since the 1970s, the Boeing company realized nearly two decades later that the airline planning requirements had changed to become more specific. As a result, by 1986, Boeing had proposed its 767-X aircraft with a longer fuselage and larger wings.

However, the market demanded wider fuselage alongside flexible interior configurations, with variations in range capability and lower operating costs. Consequently, Boeing decided to develop a new aircraft design with a twin-engine configuration, taking advantage of its prior success and reduced-cost benefits.

This was the bedrock for the launch of the Boeing 777 program at the beginning of the 90s. For the next three decades, the series 200, 300, 777F and their variations have flown all over the world and continue in production with its latest iteration, the Boeing 777X.

Launching of the Boeing 777-300


After five years of the 777 program and with series 200 in the market, Boeing’s board of directors authorized the production of the 777-300. However, while Boeing announced the launch of the aircraft on June 26, 1995, the assembly of the model did not start until April 1997.

In September of ’97, the 777-300 was ready, making its first flight the month after. By the following year, Cathay Pacific Airways (CX) had received the first delivery of the type.

Boeing 777-300 Improvements


At the time the type was introduced in the market, it was powered by two General Electric GE90, Pratt & Whitney PW4000, or Rolls-Royce Trent 800 engines.

By the 2000s, a variation of the twinjet was developed. The Boeing 777-300ER’s first delivery took place in 2004 with Air France (AF) as its first customer.

Besides the increased range of the new model of almost 2,000 nautical miles and a larger wingspan, both the -300 and the -300ER are similar. Further, the seating capacity for both models could be expanded depending on their configuration.
