The Boeing 777, first produced in 1993, is recognized as the world’s largest and longest twin-engine commercial aircraft. According to Boeing, as of August 2025, a total of 1,767 units have been delivered. In 2023, the 777 family ranked as the third-most common airliner globally and was the most popular widebody jet on the commercial market.

Among Boeing’s lineup, only the 747 surpasses the 777 in size. The Ilyushin Il-76, a Soviet-era long-range transport aircraft, is also among the world’s largest planes. It has been widely used for ramp-delivered cargo and is considered by Air Charter Service to be the most popular cargo aircraft in air transportation history.

When comparing these two large aircraft, their specifications reveal significant differences. The largest current variant of the Boeing 777 is the 777-300ER (Extended Range), which features a higher maximum takeoff weight (MTOW) and increased fuel capacity compared to previous models. Aerodynamic improvements have led to a fuel burn reduction of 1.4%, according to Flight Global.

The Il-76 has also seen several versions since its introduction in 1971. Only two of its largest variant—the Il-76MF—were built with extended fuselages and more powerful engines for military use. Russia recently invested $584 million to increase IL-76 production from seven to twenty-four units annually with plans for civilian certification and exports targeting India, Iran, and Egypt.

In terms of dimensions:

- The Boeing 777-300ER measures approximately 242 feet in length with a wingspan of over 212 feet.

- The Il-76TD measures about 152 feet in length with a wingspan just under 166 feet.

The MTOW for the 777-300ER is around 775,000 pounds compared to about 419,000 pounds for the Il-76TD.

Both aircraft serve different purposes. The Il-76 was designed as a quadjet specifically for heavy cargo transport and can operate from rough or unpaved runways—a feature that makes it suitable for delivering equipment to remote locations or providing humanitarian aid and disaster relief worldwide. Its design includes features such as electric winches and hoists for loading heavy items efficiently.

Volga Dnepr Airlines owns several Il-76s equipped with specialized loading gear: “The freight compartment of the IL-76TD-90VD is equipped with two electric winches, each with a three-tonne hauling capacity. There are four electric hoists with 10-tonne total lifting capacity, which move on two rails along the entire length of the cargo compartment and six meters beyond the ramp threshold. It is possible to load through the cargo door into the main deck of the aircraft directly from the ground or from a truck. Volga-Dnepr’s specialist loading equipment allows a single piece of cargo weighing up to 50 tonnes to be carried on board.”

For passenger comfort, however, there are clear distinctions between these aircraft types. While military versions of the Il-76 are fitted with hard benches that offer little comfort during troop transport missions, airlines operating Boeing’s widebody jets benefit from flexible cabin layouts accommodating various seating configurations—ranging from four-abreast first class pods up to ten-abreast economy class seating—and an internal cabin width exceeding 231 inches.

According to Boeing: “Boeing claims that the 777 is the most comfortable aircraft in its class, with an internal cabin width of 231.1 when outfitted in a passenger configuration.” In high-density layouts like those found on some Asian carriers’ routes between major hubs, one version can carry up to 451 passengers.

As demand for air travel continues following industry recovery after COVID-related shutdowns—seen in trends such as airlines returning older widebody jets like Airbus A380s into service—the need for high-capacity jets like both these models remains strong [https://simpleflying.com/airlines-returning-airbus-a380/]. Similarly, ongoing global logistics needs ensure continued demand for versatile freighters like the Il-76 across Europe, Africa, and Middle Eastern markets.

In summary:

While both airplanes rank among aviation’s giants due to their size and capability—the Boeing model excels at long-haul passenger operations while offering substantial payload flexibility; meanwhile, Russia’s Ilyushin design remains essential for heavy-lift missions requiring rugged performance under challenging conditions.
