History
In July 1978, Boeing announced the 7X7 twin aisle, to fill the gap between the Boeing 727 and Boeing 747 and to compete with the then new Airbus A300. At the same time, Boeing announced the 7N7 single aisle, this becoming the Boeing 757. The two crew EFIS flightdeck (with six colour CRT displays) of the Boeing 757 and 767 are very similar and as a result, after a short conversion course, pilots rated in the 757 are also qualified to fly the 767 and vice versa. In a rather unfortunate move, Boeing decided on a 198 inch cross section, giving a 186 inch internal cabin width. This limited the aircraft to seven abreast seating and - perhaps more importantly - prevented the carriage of side-by-side freight containers in the under floor holds. Airbus got this right, opting for a 222 inch cross section, giving a 208 inch internal width. Especially in military tanker/transport missions, the smaller cross section is a major disadvantage. In commercial service, the 767 was quite successful, with an order book of over 1,000 aircraft. With the 787 nearing completion, 767 orders are swindling down rapidly.

Civil versions
767-100
Projected 180 seater, designed to compete with the Airbus A310. Eventually, the model turned out to be the same size of the 757-200 and therefore cancelled.
767-200
Baseline model for 220 pax and 127,9 tonnes gross weight. Initially available as 767-200MR Medium Range (with reduced fuel capacity), 767-200HGW High Gross Weight). Later, two Extended Range models were added, the 767-200ER (MTO 156,4 tonnes and 12.000 km range) and the 767-200LR aka 767-200ER(HGW) (MTO 170,5 tonnes). Available with General Electric CF6-80C2 and Pratt & Whitney JT9D-7R4D turbofans. The 767-200PF or 767-200PC are specialised package freighters.
767-300
Stretched model for 269 pax and MTOGW of 143 tonnes. Extended range model available as 767-300ER, having a MTOGW of 172,4 tonnes. Available engines are the General Electric CF6-80 and the Pratt & Whitney PW4000. Launch customer for the 767-300F(ER) freighter was United Parcel Service. This model carries a 49 tonnes payload 5.500 km far.
767-400
Initially designated 767-300ERX. Sized between the Boeing 767-300ER and the 777-200 and aimed as direct competitor to the A330-300, the 767-400ER features a lengthened fuselage; aerodynamic improvements, including additional wing span; increased takeoff weight capability; and an all-new main landing gear. Boeing offered a 767-400ERX aka 767-400LR re-engined longer range version, in 2000. The -400ERX offered an increased maximum takeoff weight of 211 tonnes and a range of 11,400 km. However, the model was cancelled. The first airplane rolled out of the Boeing factory Aug. 26, 1999 and made its inaugural flight October 9, 1999. The 767-400ER is expected to be replaced by the 787-9.
Military versions
KC-46
On 24 February 2011, the US Air Force awarded a contract to to produce the KC-46A aerial refuelling aircraft, replacing the Eisenhower-era KC-135s and the Reagan-era KC-10s. Boeing has received the initial development contract, valued at more than $3.5 billion, to provide the first 18 new-build tankers by 2017. The Air Force intends to buy 179 of them to replace its oldest KC-135s. The KC-46 (Boeing indoor designation 767-2C) will be powered by PW4062 engines.
E-10
Multi-sensor Command and Control Aircraft (MC2A) military derative of the 767-400ER. One 767-400ER aircraft has been produced as a testbed for systems integration and is in storage pending decision on its final disposition since the E-10 program has been terminated.
E-10A
Initial model, intended to replace the E-8C Joint Stars aircraft to provide improved tracking of moving ground targets. Additionally, it will be designed to detect low-flying cruise missiles.
E-10B
Proposed spiral development to replace the Boeing E-3 Sentry AWACS airborne surveillance aircraft.
E-10C
Proposed development to replace the RC-135 Rivet Joint signals intelligence aircraft.
E-767
Airborne Early Warning & Control development of the 767-200ER, Boeing designation 767-27C. Compared to the Boeing E-3 Sentry, the E-767 offers 50 percent more floor space and nearly twice the volume. Mission equipment is installed in forward cabin to balance the weight with the rotodome on the aft fuselage. The E-767 essentially used the same avionics as the Boeing E-3 Sentry, including the Northrop Grumman AN/APY-2 radar. At 1,850 km from base, the endurance is 7 hours, increasing to 10 hours at 550 km from base. The Japanese Air Self Defence Force ordered four aircraft.
767 Air Surveillance Testbed
Developed for the Airborne Optical Adjunct project of the US Army Ballistic Missile Defence Systems Command. Two large sensors were mounted in the cupola on the top of the fuselage. The cupola is 86 feet long, 8 feet high and 10 feet wide. Hughes Aircraft Company produced the infra-red sensors and Honeywell produced the on-board data processor. The 767AOA was used to track theater ballistic missile launches in a series of tests.
767 tanker/transport modifications
KC-767A
Developed from the 767-200ER to replace the oldest KC-135E Stratotankers. Initially won by Boeing but later cancelled due to conflict of interest and a controversial lease agreement.
KC-767J
Tanker version developed for and delivered to Japan.
KC-767 Tanker/Transport
Tanker/transport development based on the 767-200ER, ordered by the Italian Air Force and the Japan Self-Defense Forces (as KC-767J).
KC-767 Advanced Tanker
In the second round for the KC-135E replacement, Boeing proposed a derative of the 767-200LRF (Long Range Freighter). This time, the contract was awarded to Airbus with its KC-30 offer. This was, however, overturned by the GAO, which concluded that the selection of the competing Airbus KC-30. The competition was opened again a eventually won by Boeing with its KC-46 proposal.
767 MMTT
Multi Missions Tranker Transport modification, proposed by IAI Bedek in 2012. The design as based on the 767-200ER modified for Colombia in 2010 and has a remotely controlled refueling boom and AAR refueling pods under the wings. In 2013, the Brazilian air force selected IAI Bedek to convert two 767-300ER models into aerial refueling tanker transports.
