Boeing 737-800BCF vs. Boeing 757F

The Boeing 737-800BCF (Boeing Converted Freighter) represents a pivotal innovation in the cargo aircraft segment, being a converted variant of the popular Boeing 737-800 passenger aircraft. Adapted for freight transport, it merges the proven efficiency of its predecessor with the specific needs of cargo operations.

Production History: The development of the 737-800BCF was initiated by Boeing in early 2016, responding to the growing demand for a modern, efficient medium-sized freighter. The program aimed to repurpose the 737-800 for cargo use, leveraging the aircraft's existing performance strengths. GE Capital Aviation Services (GECAS) received the first converted aircraft in April 2018, marking the introduction of this model into the global air freight market. Since its inception, the program has seen significant interest, with Boeing receiving over 120 orders for the 737-800BCF by September 2019, indicating its strong market reception.

Design Features: The 737-800BCF maintains a similar structural design to the 737-800, featuring a length of 39.5 meters, a wingspan of 35.8 meters, and a height of 12.6 meters. Key adaptations for its freighter role include the installation of a large main-deck cargo door, a reinforced floor, and a tailored cargo-handling system. The aircraft's tricycle landing gear system, equipped with oleo-pneumatic shock absorbers, supports its freight operations. The similarity in design to the Next-Generation 737 passenger variants ensures reduced maintenance and operational costs due to shared components and systems.

Operational History: The 737-800BCF quickly found its niche in the market, primarily serving in transporting express cargo on domestic and short-haul international routes. Its operational efficiency, combined with the capability to handle a variety of cargo types, has made it a preferred choice for cargo operators worldwide. The aircraft's entry into service has been marked by its adoption by numerous airlines and freight operators, further establishing the 737-800BCF as a reliable workhorse in the air freight industry.

Similar Freighter Models: In the realm of medium-sized freighters, the 737-800BCF competes with models like the Airbus A321 Freighter and other converted variants of similar-sized passenger aircraft. While each model has its unique features, the 737-800BCF stands out for its combination of efficient performance, cargo capacity, and the operational reliability inherited from the Boeing 737 family.

The Boeing 757-200 Package Freighter (PF) is a cargo variant of the Boeing 757-200 passenger aircraft, designed for transporting cargo over medium and long distances. With its long narrow-body design, it serves as a versatile option in the air cargo sector.

Production History: The Boeing 757PF, introduced in 1987 and produced until 2004, is a direct adaptation of the passenger version of the 757-200. A total of 80 cargo versions of this model were built, reflecting its popularity and utility in the freight transportation industry. The aircraft has seen various modifications and variants over the years. Many passenger models have also been converted into freighters​​​​ once they exceed their passenger lifespan.

Design Features: The 757 freighter features a large main deck cargo door on the forward port-side fuselage. Next to this is an normal exit door used by the pilots, with all other emergency exits omitted. Similarly, all cabin windows and passenger amenities were left uninstalled. The Boeing 757-200PF has a length of 47.3 meters, a wingspan of 38 meters, and a height of 13.6 meters. It is equipped with either Rolls-Royce RB211-535E4 or Pratt & Whitney PW2000 engines. The aircraft's maximum takeoff weight is 127 tons, and it can carry up to 43 tons of cargo. The cargo hold dimensions are 33.2 m x 3.5 m x 2.4 m, accommodating 15 pallets or 39,100 kg of cargo​​.

Operational History: The Boeing 757-200 Freighter has been a mainstay in the fleets of various cargo operators. Its ability to handle diverse cargo types, from mail and goods to airline supplies, has made it a reliable choice for different logistical needs. Its performance and capacity have been especially beneficial for medium-range cargo routes​​​​. Freight operators of the 757 include UPS, FedEx, DHL, and Cargojet.

Similar Freighter Models: Comparable aircraft to the Boeing 757-200PF include the Airbus A321F, Boeing 737 Freighter, and Tupolev Tu-204. However, the 757 plays a very unique role in the air transport industry due to its size and performance capabilities. With 757s aging and on their way out of service, they will most likely be replaced by more fuel efficient narrowbodies like the 737 and A320, or newer widebodies like the 767s and A330.
