Officially known as Royal Brunei Air Force Base, Rimba, (), commonly known as Rimba Air Force Base (), abbreviated: "", and occasionally known as Rimba Airbase; it is the military headquarters and main operating airbase of the Royal Brunei Air Force (RBAirF, originally - ATUDB, from 2005 to - TUDB). It is located at Rimba opposite, and sharing its main runway of with the Brunei International Airport (BIA), at Bandar Seri Begawan, in the Brunei-Muara District of the sultanate of Brunei Darussalam.
History and operations.
Aviation in the sultanate of Brunei arose due to a government desire to provide medical services in the rural areas of its territory. Two Sikorsky S55 helicopters were contracted from the World Wide Helicopter Company to fly doctors by helicopter to remote areas, particularly those which were inaccessible by road. In 1966, this service was taken over by three British pilots from the Royal Air Force (RAF), operating two RAF Westland Whirlwind helicopters, thereby signifying the start of military aviation in Brunei, officially becoming a helicopter platoon. Three years later, in 1969, it was officially named the Air Wing.
In 1970, prior to Rimba Air Force Base, the military Air Wing of Brunei then started to operate a pair of Bell 205 helicopters from Berakas Garrison, forming No. 1 Squadron. These were subsequently replaced in 1974 by Bell 212 helicopters. No. 2 Squadron was formed in 1981, equipped with German Bolkow BO105 helicopters operating in the close air support (CAS) role.
In 1984, as a result of the independence of Brunei Darussalam from the United Kingdom (UK), the Air Wing came under the official command of Command Task Force, Royal Brunei Armed Forces (RBAF). On 1 October 1991, the Air Wing, Royal Brunei Armed Forces became an independent service (air force) of Royal Brunei Armed Forces, and was officially named the Royal Brunei Air Force (RBAirF), or "Angkatan Tentera Udara Diraja Brunei" (ATUDB) in Malay. It was also operating from Penanjong Garrison during this period.
1997 saw the arrival of Blackhawk S70A-14 helicopters, and more significantly, a fixed-wing aircraft, namely the CN 235 transport aircraft. This resulted in the official formation of No. 4 Squadron and No. 5 Squadron on 12 September 1997. Fixed-wing training aircraft were acquired in 1998, the Pilatus PC-7 Mk.II. Security was enhanced on 4 January 1999, with the formation of an Air Regiment and a Base Defence Squadron.
Following the change on 1 January 2005 of the official Malay name of the Royal Brunei Air Force to "Tentera Udara Diraja Brunei" (TUDB), the first of the three ordered Sikorsky S-92s by Brunei Shell Petroleum (BSP) arrived at Air Force Base, Rimba, on 25 February 2007, before being transferred to Anduki Airfield (WBAK). These aircraft were transported by an Antonov An-124 from Bradley International Airport, Windsor Locks, Connecticut, USA. During BRIDEX 2011, the United States Air Force (USAF) made their first ever participation in the event, with General Dynamics F-16s from Misawa Air Base, Japan, conducting aerial demonstrations over Air Force Base, Rimba. Additionally, the Republic of Singapore Air Force (RSAF) sent a Boeing CH-47SD/F Chinook for static display within Hangar B of the airbase.
On the morning of 20 July 2012, having departing Air Force Base, Rimba at 08:55, a RBAirF Bell 212 was due to return to the airbase later that same morning, but subsequently was found crashed with the loss of 12 out of 14 military personnel in Rampayoh, Mukim Labi. Investigations by the Supreme Board of Inquiry of the Royal Brunei Armed Forces (RBAF) concluded that the crash was caused by human error whilst in flight; specifically 'unauthorised low-level flying' which resulted in a controlled flight into terrain (CFIT).
The fourth BRIDEX meet in 2013 seen the introduction of the newer Blackhawk variant into the Royal Brunei Air Force, the Blackhawk S70i, unveiled by His Majesty the Sultan of Brunei. This new acquisition of the S70i marked the end and retirement of the entire fleet of Bell 212, which spanned forty years service in the RBAirF. BRIDEX 2013 also had participation from the United States of America, by sending a single USAF C-17 Globemaster III of the 545th Airlift Squadron from Joint Base Pearl Harbor–Hickam, Hawaii, a United States Marine Corps (USMC) MV-22B Osprey, and a KC-130J Super Hercules.
On 24 February 2016, eight Republic of Korea Air Force (RoKAF) KAI T-50B of the 53rd Air Demonstration Group, 'Black Eagles' made a planned refuelling stop at the airbase, and later on 24 June, the RBAirF revealed a 50th anniversary monument at the Air Movement Centre (AMC), Air Force Base, Rimba. Later that year on 16 November 2016, four Royal Air Force (RAF) Eurofighter Typhoon multi-role fighter jets supported by an RAF Voyager tanker-transport visited the airbase. On 18 July 2017, an RAF A400M Atlas C1 from No. 70 Squadron RAF visited the airbase, and later from 27 until 29 July 2017, the Japan Air-Self Defense Force (JASDF) Boeing KC-767 made a goodwill visit to the base.

A United States and Brunei joint exercise Cooperation Afloat Readiness and Training (CARAT) was held at the base on 22 October 2019.

On 2 November 2019 at 16:55, the main gate of Royal Brunei Air Force Base, Rimba was damaged when a man in a hijacked car used it to ram into the main gate "a few times". The car, with a young boy inside, was hijacked by 24 year old Muhammad Firdaus bin Mohammad Salleh, and the impact caused the main gate to fall, which then damaged two cars parked nearby. Bin Mohammad Salleh failed to enter a plea to the charge of 'committing an act endangering the lives of the public' when appearing at the Magistrates' Court on 4 November 2019. The defendant could face a fine and up to three years imprisonment if convicted, his case was referred to the Deputy Public Prosecutor for a further hearing on 11 November 2019, which was then adjourned by three weeks until 2 December. On 8 February 2021, local man bin Mohamad Salleh was given a custodial sentence of two years six months imprisonment plus three strokes of the cane after pleading guilty at the High Court.
