Rolls-Royce BR710 — Aircraft Engine
Open in interactive gallery →

The Rolls-Royce BR710 is the first member of the BR700 family of medium-thrust turbofans built by Rolls-Royce Deutschland at Dahlewitz, near Berlin. The BR700 line began life in 1990 as a joint venture between BMW and Rolls-Royce plc — BMW Rolls-Royce GmbH — to develop a clean-sheet engine for the emerging long-range business-jet market. BMW exited the venture in 2000, leaving Rolls-Royce Deutschland as the sole owner of what is today one of the company's most successful product lines. The BR710 first ran in 1995, certified in 1996, and entered service the same year on the Gulfstream V and the Bombardier Global Express.

The engine is a two-spool unbypass-free design with a 48-inch single-stage wide-chord fan, a 10-stage HP compressor, an annular combustor, a two-stage HP turbine, a three-stage LP turbine, and FADEC control. Bypass ratio is around 4.2:1 — high for its thrust class — giving lower fuel burn and a quieter signature than the competing Pratt & Whitney Canada PW305 or PW306 it displaced on long-range business jets. Take-off thrust on the BR710A1-10 variant is around 14,750 lbf flat-rated to ISA+15°C, and the BR710C4-11 variant on the Global Express delivers around 14,750 lbf with a slightly different bleed schedule. Time on wing routinely exceeds 12,000 hours between shop visits in business-jet service, well above turbofan-class norms.

The BR700 family quickly expanded. The BR715 (1999) supplied around 21,000 lbf for the 100-seat Boeing 717 and the McDonnell Douglas MD-95, an application that closed when 717 production ended in 2006. The BR725 (2008) lifted thrust to around 17,000 lbf for the Gulfstream G650 and shares core technology with the BR710 but with a larger fan and refined HP compressor. The BR725 is also the basis for the Rolls-Royce F130 selected by the U.S. Air Force in 2021 to re-engine the entire B-52 Stratofortress fleet — eight F130s per bomber, replacing the original Pratt & Whitney TF33 turbofans that have powered the B-52 since the early 1960s. The B-52J re-engining is the largest single contract in Rolls-Royce Deutschland's history.

The BR710 itself powers four major airframes in 2026: the Gulfstream V (1996-2002), the Gulfstream G550 (2003-2021), and Bombardier's Global Express and Global 5000/6000 family (1999-2018). Military derivatives include the U.S. Navy / Air Force C-37A and C-37B VIP transports (G550-derived), the British RC-135W Rivet Joint signals-intelligence aircraft (Gulfstream V-derived), and the EC-37B Compass Call electronic-attack platform (G550-derived) entering service from 2023. By 2026 around 3,500 BR710s had been built — the most produced engine in Rolls-Royce Deutschland's history before the F130 fleet takes that crown later in the decade.

The Pearl 700 family — Pearl 15, Pearl 700, Pearl 10X — represents the evolutionary next step beyond the BR700 series and powers the Bombardier Global 5500/6500/7500 and the Gulfstream G700/G800. Although marketed under the Pearl name rather than BR700, the Pearl engines share core architecture and the Dahlewitz production line. The BR710 thus stands as the founder of a 30-year-long product family that took Rolls-Royce Deutschland from a 1990 BMW joint-venture startup to the dominant supplier of large-cabin business-jet propulsion.

For Kids — a shorter, friendlier version

The Rolls-Royce BR710 is a jet engine made to power big business jets. It was built at a factory in Dahlewitz, near Berlin, Germany. It belongs to a family of engines called the BR700 line.

The BR710 story started in 1990. Two famous companies, BMW and Rolls-Royce, teamed up to build a brand-new engine. BMW left the team in 2000, and Rolls-Royce kept going alone. The engine first ran in 1995 and was ready to fly in 1996.

The BR710 powers some very fancy jets. You can find it on the Gulfstream V and the Bombardier Global Express. These are long-range jets that can fly people across oceans without stopping. The engine is smaller than a car, yet it pushes a whole jet through the sky.

Inside the engine, a big fan at the front pulls in air. The air gets squeezed, mixed with fuel, and burned to make power. A special computer system called FADEC helps keep everything running smoothly and safely.

The BR710 uses less fuel than older engines of the same size. It is also quieter, which is great for passengers and people living near airports. That mix of saving fuel and staying quiet made it very popular with jet makers.

Fun Facts

  • The BR710 first ran in 1995 — the same year the PlayStation 1 launched in North America!
  • The fan at the front of the engine is 48 inches wide — bigger than most kids are tall!
  • BMW and Rolls-Royce worked together to design the BR710 from scratch in 1990.
  • The BR710 can push with about 14,750 pounds of force at takeoff — imagine 14,750 bags of sugar pushing you forward!
  • The engine has a bypass ratio of about 4 to 1, which helps it burn less fuel and stay quieter.
  • The BR710 powers scouting aircraft used by the military, like the RC-135W and the EC-37B.
  • Rolls-Royce built the BR710 at Dahlewitz, a town near Berlin, Germany.
  • The Bombardier Global Express uses a special version of the BR710 made just for that jet.

Kids’ Questions

What kind of planes use the BR710 engine?

The BR710 powers long-range business jets like the Gulfstream V and the Bombardier Global Express. These jets can fly very far without stopping to refuel. Some military planes, like the RC-135W and the EC-37B, also use this engine.

Why is the BR710 better than older engines?

The BR710 burns less fuel than many older engines of the same size. It is also much quieter, which is nice for passengers and people near airports. That made it a great choice for fancy long-range jets.

Who built the BR710 engine?

BMW and Rolls-Royce started building the BR710 together in 1990. BMW left the project in 2000, and Rolls-Royce finished the work alone. The engine is made at a factory near Berlin, Germany.

Variants

BR710A1-10 (Gulfstream V / G550)
Initial 1996 variant flat-rated to around 14,750 lbf take-off thrust. Standard powerplant for the Gulfstream V (1996-2002) and the G550 (2003-2021). Time-on-wing exceeds 12,000 hours in typical business-jet service.
BR710C4-11 (Bombardier Global Express family)
Slightly different bleed and FADEC schedule for the Bombardier Global Express, Global 5000, and Global 6000. Same fan and core as the A1-10. In production 1999-2018.
BR710 Tay 611-8C ancestry
Not a true BR710 variant but worth noting — Rolls-Royce drew on Tay turbofan experience for the BR710's core architecture, particularly the HP compressor blading and combustor cooling design.
BR725 (Gulfstream G650)
Higher-thrust BR700 family member at around 17,000 lbf, with a larger fan and updated HP compressor. Powers the Gulfstream G650 / G650ER from 2012.
F130 (B-52J)
Military derivative of the BR725 selected by the U.S. Air Force in 2021 to re-engine the entire B-52 fleet. Eight F130s per bomber replace the 1960s-era TF33s, extending the B-52's service life past 2050. Final delivery in the early 2030s.

Notable Operators

Gulfstream large-cabin family
Gulfstream V (1996-2002) and Gulfstream G550 (2003-2021) — around 1,500 BR710A1-10s delivered. The G550's military derivatives, including the U.S. C-37A and C-37B VIP transports, also use the BR710A1-10.
Bombardier Global Express family
Global Express (1999-2003), Global Express XRS, Global 5000, and Global 6000 — around 1,600 BR710C4-11s delivered through 2018. The line was replaced from 2019 by the Pearl 15-powered Global 5500/6500.
Military intelligence and electronic-warfare platforms
RAF and U.S. RC-135W Rivet Joint signals-intelligence aircraft (Gulfstream V airframes converted), U.S. EC-37B Compass Call electronic-attack jets (G550-based, replacing the EC-130H from 2023), and several VIP-transport variants used by the U.S., German, and Israeli governments.

Frequently Asked Questions

Who actually builds the BR710?

Rolls-Royce Deutschland Ltd & Co KG at its Dahlewitz site near Berlin, on land that was originally the Deutsche Versuchsanstalt für Luftfahrt aerospace research centre. The company started in 1990 as BMW Rolls-Royce GmbH, a 50:50 joint venture; BMW exited in 2000 and Rolls-Royce became sole owner. Dahlewitz now builds the BR710, BR725, F130, Pearl 15, Pearl 700, and Pearl 10X engines, plus the M250 turboshaft programme (per Rolls-Royce Dahlewitz site information).

How does the BR710 fit into the BR700 family lineage?

The BR700 family is now a 30-year product line: BR710 (1996, business-jet baseline), BR715 (1999, 100-seat 717), BR725 (2008, G650), F130 (2021, B-52 re-engine), and the Pearl 15/700/10X (2018-2024, business-jet successors). All share core architecture, Dahlewitz production, and the same FADEC family. The Pearl marketing name signals the updated core; the engines are kin rather than clean-sheet replacements.

Why was the BR725-derived F130 chosen over a clean-sheet engine for the B-52?

The U.S. Air Force ran the B-52 Commercial Engine Replacement Programme (CERP) from 2017 to 2021 looking at modern commercial-derivative turbofans. Pratt & Whitney's PW815 and Rolls-Royce's F130 were the finalists; the F130 won in September 2021 on lower fuel burn, higher commonality with civil engines already in U.S. commercial service, and a proven Dahlewitz production line. The contract covers around 600 engines for the 76-aircraft B-52J fleet through the early 2030s (per the U.S. Air Force CERP announcement).

What is the time on wing for a BR710?

Routinely above 12,000 hours between shop visits in typical Gulfstream V / G550 / Global Express business-jet service. Some fleet engines have passed 18,000 hours without a major overhaul. The high time-on-wing reflects modest cruise thrust setting, low cycle counts versus short-haul jets (fewer take-offs per day), and Rolls-Royce's TotalCare maintenance model that smooths out failure modes through condition-based monitoring.

Is the BR710 still in production?

Production ended in 2021 with the last Gulfstream G550 deliveries. The Bombardier Global Express line had already moved to the Pearl 15 in 2018. Rolls-Royce continues to manufacture spare parts and support around 3,500 BR710s in service worldwide under long-term TotalCare contracts; with typical 20,000-hour engine lives the fleet will remain active well into the 2040s.
