. The engine was more powerful but had a diameter 2.75 inches (69.9 mm) larger, too big to readily fit into the Harrier.

A joint American and British team completed a project document defining an Advanced Harrier with the Pegasus 15 engine in December 1973. The Advanced Harrier was intended to replace original RAF and USMC Harriers, as well as the latter's A-4s. The aim of the Advanced Harrier was to double the AV-8's payload and range capabilities, and was therefore unofficially named "AV-16". The British government pulled out of the project in March 1975 due to decreased defense funding, rising costs, and a small 60-aircraft requirement by the RAF. The US was unwilling to fund development by itself, and ended the project later that year.

The two companies took different paths toward an enhanced Harrier. Hawker Siddeley focused on a new larger wing that could be retrofitted to existing operational aircraft, while McDonnell Douglas independently undertook a less ambitious, though still expensive, project catering to the needs of the US military. Using knowledge gleaned from the AV-16 effort, though dropping some items—such as the larger Rolls-Royce Pegasus engine—McDonnell Douglas kept the basic structure and engine for an aircraft tailored for the USMC.

. Rolls-Royce had previously absorbed Bristol Siddeley.

The US Navy, which traditionally procures military aircraft for the Marines, insisted that the new design be verified with flight testing. To do this, McDonnell Douglas modified two AV-8As with new wings, modified intakes, redesigned exhaust nozzles, and other aerodynamic refinements; the modified forward fuselage and cockpit were not incorporated on these prototypes. Designated YAV-8B, the first converted aircraft flew on 9 November 1978, followed by the second on 19 February 1979; the second aircraft crashed in November due to engine flameout

, somewhat hampering the aircraft's maximum speed. Refinements to the aerodynamic profile yielded little improvement. Positive results in other areas, including payload, range and V/STOL performance, led to the award of a development contract in 1979; the contract called for 12 aircraft in the first batch, and a further 324 thereafter.
Four full-scale development (FSD) aircraft were constructed. The first of these (BuNo 161396), used mainly for testing performance and handling qualities, took its maiden flight on 5 November 1981. The second and third FSD aircraft, which introduced wing leading edge root extensions

Further developments

During the initial pilot conversion course, it became apparent that the AV-8B exhibited different flight characteristics from the AV-8A, and that the use of a digital

 cockpit instead of the analog cockpit of the TAV-8A also necessitated additional training. Consequently, in 1984, money for eight AV-8Bs was diverted to the development of a two-seat TAV-8B dedicated trainer. The first of the twenty-eight TAV-8Bs eventually procured had its maiden flight on 21 October 1986. This aircraft was delivered to VMAT-203 on 24 July 1987. The TAV-8B was also ordered by Italy and Spain.

In 1985, McDonnell Douglas commenced work on a night-attack variant of the Harrier II; the company and BAe had been encouraged to continue development by export interest from Brazil, Japan and Italy

. The USMC ordered 66 AV-8B(NA)s. The 87th production AV-8B therefore became the first Harrier II to be modified with equipment for night attacks, and rolled off the St. Louis production line in June 1987. Flight tests proved successful and the night attack capability was validated. In September 1989, the first AV-8B(NA) was delivered to the Marine Corps. An equivalent version to the AV-8B(NA) also served with the RAF under the designation GR Mk.7; earlier GR Mk.5 aircraft were subsequently upgraded to GR Mk. 7 standards.

In June 1987, as a private venture, BAe, McDonnell Douglas and Smiths Industries signed an MoU

 for the development of what was to become the AV-8B Plus. This was endorsed by the USMC, and, after much consideration, the Spanish and Italian navies developed a joint requirement for a fleet of air-defense Harriers. The United States, Spain and Italy signed an MoU in September 1990 to define the responsibilities of the three countries and establish a Joint Program Office to manage the program. On 30 November 1990, the US Navy, acting as an agent for the three participating countries, awarded McDonnell Douglas the contract to develop the improved Harrier. This was followed by an order from the USMC in December 1990, which included 30 new aircraft, as well as 72 rebuilt aircraft. The Italians ordered 16 Harrier II Plus and two twin-seat TAV-8B aircraft, while the Spaniards signed a contract for eight aircraft. Production of the AV-8B Harrier II Plus would be conducted, in addition to McDonnell Douglas' St. Louis plant, at CASA's facility in Seville

, Italy. The UK also participated in the program by manufacturing components for the AV-8B.
Authorization for production was given on 3 June 1992. The maiden flight of the prototype (164129) took place on 22 September that year, marking the start of a successful flight test program. The first production aircraft was delivered to St. Louis and, on 17 March 1993, performed its first flight. Deliveries of new aircraft took place from April 1993 to 1995. At the same time, the plans to remanufacture existing AV-8Bs to the Plus standard proceeded. The Defense Acquisition Board, on 11 March 1994, approved the program, which initially involved 70 aircraft, with four converted in financial year 1994. The program aimed to rebuild aircraft with refurbished components to enhance or add capabilities at a fraction of the cost of new-built aircraft. Conversion began in April 1994, and the first aircraft was delivered to the USMC in January 1996.

Despite the apparent advantages of the program, in March 1996 the General Accounting Office stated that it was more financially sound to buy the Harrier II Plus outright under a procurement program than to remanufacture existing AV-8Bs. The Navy estimated the cost for remanufacture of each aircraft to be $23–30 million, instead of $30 million for each new-built aircraft; the GAO estimated the cost per new aircraft at $24 million. Nevertheless, the program continued, and in 2003, the 72nd and last remanufactured AV-8B was delivered to the USMC. Spain also participated in the program, with the delivery of its last refurbished aircraft occurring in December 2003, which marked the end of the AV-8B's production.

Ed Harper, general manager for the McDonnell Douglas Harrier II development program, summarized: "The AV-8B looks a lot like the original Harrier and it uses the same operating fundamentals. It just uses them a lot better". The cockpit was elevated to give the pilot an improved all-round view.

The trainer version of the AV-8B is the TAV-8B, seating two pilots in tandem. Among other changes, the forward fuselage features a 3 ft 11 in (1.19 m) extension to accommodate the second cockpit. To compensate for the slight loss of directional stability, the vertical stabilizer's area was enlarged through increases in chord (length of the wing's root) and height. USMC TAV-8Bs feature the AV-8B's digital cockpit and new systems, but have only two hardpoint

United States Marine Corps

To prepare for USMC service, the AV-8B underwent the standard rigorous evaluations. In the operational evaluation (OPEVAL), lasting from 31 August 1984 to 30 March 1985, four pilots and a group of maintenance and support personnel put the aircraft under combat type conditions. The aircraft was graded against measures such as the ability to meet its mission requirements for navigating, acquiring targets, delivering weapons, and evading and surviving enemy actions, all at the specified range and payload performance. The first phase of OPEVAL, running until 1 February 1985, required the AV-8B to fly close and deep air support missions in concert with other close air support aircraft, as well as flying battlefield interdiction

In a single sortie from USS Bonhomme Richard, a wave of Harriers inflicted heavy damage on a Republican Guard tank battalion in advance of a major ground assault on Al Kut. Harriers regularly operated in close support roles for friendly tanks, usually with one carrying a LITENING pod. Despite the Harrier's high marks, the limited amount of time that each aircraft could remain on station, around 15–20 minutes, led to some calls from within the USMC for AC-130 gunships to be procured; the AC-130 could loiter for six hours, and had a heavier close air support capability than the AV-8B. AV-8Bs were later used in combination with artillery to provide constant fire support for ground forces during heavy fighting in 2004 around the insurgent stronghold of Fallujah

reported in 2003 that the Harrier family had the highest rate of major accidents among military aircraft in service then, with 148 accidents and 45 people killed. Aviation author Lon Nordeen notes that several other USMC single-engine strike aircraft, like the Douglas A-4 Skyhawk and LTV A-7 Corsair II, had worse accident rates. The Harrier's high accident rate is largely due to the higher percentage of time it spends taking off and landing, which are the most critical times in flight. The AV-8B is to be replaced by the F-35B version of the Lockheed Martin F-35 Lightning II, which had been slated to enter service in 2012. The Marine Corps has argued strongly in favor of the development of the F-35B, considering the Harrier's performance in Iraq, including its ability to use forward operating bases, to have reinforced the need for a V/STOL aircraft in the USMC arsenal.
