Boeing started making the 737 back in the ’60s, and guess what? They’re still making this well-liked single-aisle plane today. Over the years, the 737 has seen a bunch of updates, leading to four main generations: the original, classic, NG, and the MAX. In total, we’ve got 13 different versions of this aircraft. So, let’s get to know these Boeing 737 generations a bit better, shall we?
The Original 737 Models
The 737-100 was the first model, and it started flying in 1968. It was a small aircraft, but it served its purpose well. Lufthansa was the first airline to operate it. The original 737 featured thrust reversers that were later improved for better efficiency. The 737-200 followed, offering a longer fuselage and additional upgrades. It was so adaptable that it could even operate on gravel runways.
The 737 Classic Series
Moving to the 1980s, Boeing introduced the 737 Classic series, which included the 737-300, -400, and -500 models. These aircraft were larger, more efficient, and featured new CFM56 engines. Airlines began retiring older models in favor of these new versions. An optional winglet upgrade was also available for the Classic series, enhancing their efficiency further.
The 737 Next-Generation (NG) Series
In the late 1990s, the 737 Next-Gen, or 737NG, models were introduced. These were the -600, -700, -800, and -900 variants. They featured a redesigned wing, improved engines, and a modern cockpit. The 737-800 became extremely popular and is still in widespread use today. The Next-Gen series also offered the 737-900ER, capable of carrying more passengers and covering longer distances.
The 737 MAX Series
The most recent addition to the 737 family is the MAX series. These aircraft come with even more advanced engines and improved aerodynamics. However, they have also faced challenges, including a worldwide grounding following two fatal crashes. After adjustments and testing, they have returned to service.
