In 1981 and 1982, there were two accidental launches of Harpoon missiles: USS Coontz (DDG-40)#DDG-40 , one by the United States Navy which caused no damage and 1982 Harpoon missile misfire incident, the other by the Danish Navy, which destroyed and damaged buildings in the recreational housing area Lumsås. The Danish missile was later known as the ''hovsa-missile'' (''hovsa'' being the Danish language, Danish term for ''oops'').

Harpoon Block 1D
This version featured a larger fuel tank and re-attack capability, but was not produced in large numbers because its intended mission (warfare with the Warsaw Pact countries of Eastern Europe) was considered to be unlikely following the Dissolution of the Soviet Union. Range is . Block 1D missiles were designated RGM/AGM-84F.SLAM ATA (Block 1G)
This version, under development, gives the SLAM a re-attack capability, as well as an image comparison capability similar to the Tomahawk cruise missile; that is, the weapon can compare the target scene in front of it with an image stored in its onboard computer during terminal phase target acquisition and lock on (this is known as DSMAC). Block 1G missiles AGM/RGM/UGM-84G; the original AGM-84H/K SLAM-ER, SLAM-ER missiles were designated AGM-84H (2000-2002) and later ones the AGM-84K (2002 onwards).Harpoon Block 1J
Block 1J was a proposal for a further upgrade, AGM/RGM/UGM-84J Harpoon (or Harpoon 2000), for use against both ship and land targets.Harpoon Block II
In production at Boeing facilities in Saint Charles, Missouri, is the Harpoon Block II, intended to offer an expanded engagement envelope, enhanced resistance to electronic countermeasures and improved targeting. Specifically, the Harpoon was initially designed as an open-ocean weapon. The Block II missiles continue progress begun with Block IE, and the Block II missile provides the Harpoon with a littoral-water anti-ship capability. The key improvements of the Harpoon Block II are obtained by incorporating the inertial measurement unit from the Joint Direct Attack Munition program, and the software, computer, Global Positioning System (GPS)/inertial navigation system and GPS antenna/receiver from the SLAM Expanded Response (SLAM-ER), an upgrade to the SLAM. The US Navy awarded a $120 million contract to Boeing in July 2011 for the production of about 60 Block II Harpoon missiles, including missiles for 6 foreign militaries. India acquired 24 Harpoon Block II missiles to arm its maritime strike SEPECAT Jaguar, Jaguar fighters in a deal worth $170 million through the Foreign Military Sales system. In December 2010, the Defense Security Cooperation Agency (DSCA) notified U.S. Congress of a possible sale of 21 additional AGM-84L Harpoon Block II Missiles and associated equipment, parts and logistical support for a complete package worth approximately $200 million; the Indian government intends to use these missiles on its Indian Navy P-8I Neptune maritime patrol aircraft. The Indian Navy is also planning to upgrade the fleet of four submarines – – with tube-launched Harpoon missiles. Harpoon Block II missiles are designated AGM/RGM/UGM-84L. In early 2018, the U.S. State Department approved the sale of Harpoon Block II to the Mexican Navy for use on their future Sigma-class design frigates, the first of which is being built by Damen Schelde Naval Shipbuilding.Harpoon Block II+
On 18 November 2015, the U.S. Navy tested the AGM-84N Harpoon Block II+ missile against a moving ship target. The Block II+ incorporates an improved GPS guidance kit and a net-enabled data-link that allows the missile to receive in-flight targeting updates. The Block II+ is planned to enter service in 2017. The USN intends to deploy the Harpoon Block II+ in late FY2018 by upgrading its existing inventory of Harpoon IC missiles.Harpoon Block III
Harpoon Block III was intended to be an upgrade package to the existing USN Block 1C missiles and Command Launch Systems (CLS) for guided missile cruisers, guided missile destroyers, and the F/A-18E/F Super Hornet fighter aircraft. After experiencing an increase in the scope of required government ship integration, test and evaluation, and a delay in development of a data-link, the Harpoon Block III program was canceled by the U.S. Navy in April 2009.Harpoon Block II+ ER
In April 2015, Boeing unveiled a modified version of the RGM-84 it called the Harpoon Next Generation. It increases the ship-launched Harpoon missile's range from the Block II's to , along with a new lighter warhead and a more fuel-efficient engine with electronic fuel controls. Boeing offered the missile as the U.S. Navy's Littoral Combat Ship frigate upgrade over-the-horizon anti-ship missile as a cost-effective missile upgrade option; complete Next Gen Harpoons would cost approximately as much as a Block II at $1.2 million each, with upgrades for an existing missile costing half that. The version is also called the Harpoon Block II+ ER. Boeing claims the Block II+ ER is superior to the Naval Strike Missile through its improved turbojet giving it greater range and active radar-homing seeker for all-weather operation, as well as a lighter but "more lethal" warhead. Test shots in 2017 had been confirmed. In May 2017, Boeing revealed it was no longer offering the upgraded Harpoon for the frigate OTH missile requirement, but would continue development of it.Operational history

sank at least two Libyan patrol boats in the Gulf of Sidra. Two Harpoon missiles were launched from the cruiser with no confirmed results and several others from A-6 Intruder aircraft that were said to have hit their targets. Initial reports claimed that USS ''Yorktown'' scored hits on a patrol boat, but action reports indicated that the target may have been a false one and that no ships were hit by those missiles.
In 1988, Harpoon missiles were used by the U.S. to sink the Iranian frigate IRIS Sahand (1969), ''Sahand'' during Operation Praying Mantis. Another was fired at the Iranian La Combattante IIa-class fast attack craft, ''Kaman''-class missile boat ''Joshan'', but failed to strike because the fast attack craft had already been mostly sunk by RIM-66 Standard missiles. An Iranian-owned Harpoon missile was also fired at the guided missile cruiser . The missile was successfully lured away by Chaff (countermeasure), chaff.

fighter from the aircraft carrier killed one sailor when it struck the merchant ship ''Jagvivek'', a long Indian-owned ship, during an exercise at the Pacific Missile Range Facility, Pacific Missile Range near Kauai, Hawaii. A Notice to Mariners had been issued warning of the danger, but ''Jagvivek'' left port before receiving the communication and subsequently strayed into the test range area, and the Harpoon missile, loaded just with an inert dummy warhead, locked onto it instead of its intended target.
The UGM-84A undersea-launched Harpoon version was retired from U.S. Navy service in 1997, leaving the U.S. submarine force without an anti-ship missile, a capability that is not planned to be reintroduced until the BGM-109 Tomahawk, Block IV Tomahawk is modified with a moving target maritime attack feature in 2021. During RIMPAC 2018 a UGM-84 Harpoon was fired by USS ''Olympia'' at the ex-USS ''Racine''. The U.S. Navy plans to refurbish and recertify UGM-84 Harpoon missiles to reintroduce the capability to s. A $10 million contract was awarded to Boeing in January 2021 to deliver the missiles by the end of the year.
In June 2009, it was reported by an American newspaper, citing unnamed officials from the Obama administration and the U.S. Congress, that the American government had accused Pakistan of illegally modifying some older Harpoon missiles to strike land targets. Pakistani officials denied this and they claimed that the US was referring to a new Pakistani-designed missile. Some international experts were also reported to be skeptical of the accusations. Robert Hewson, editor of Jane's Information Group, Jane's Air Launched Weapons, pointed out that the Harpoon is not suitable for the land-attack role due to deficiency in range. He also stated that Pakistan was already armed with more sophisticated missiles of Pakistani or Chinese design and, therefore, "beyond the need to reverse-engineer old US kit." Hewson offered that the missile tested by Pakistan was part of an undertaking to develop conventionally armed missiles, capable of being air- or surface-launched, to counter its rival India's missile arsenal. It was later stated that Pakistan and the US administration had reached some sort of agreement allowing US officials to inspect Pakistan's inventory of Harpoon missiles, and the issue had been resolved.
The Harpoon missile has also emerged as a preferred choice for several foreign countries under the Foreign Military Sales (FMS) route. In 2020 its manufacturer Boeing won two major contracts for supplying Harpoon missiles to Saudi Arabia and six other partner nations under a $3.1 billion deal.
India will also receive Harpoon missiles under FMS in a $155 million deal.
In late May 2022, Denmark sent Harpoon launchers and missiles to Ukraine to help 2022 Russian invasion of Ukraine, their war effort, and shortly after, the Netherlands sent additional missiles. In mid-June 2022, the US announced that they would supply Ukraine with Harpoon launchers and missiles, and the UK Defence Secretary said that they also were looking into supplying Ukraine with the missiles. On 17 June, Ukraine claimed to have sunk the tugboat with two Harpoon missiles. In a tweet they said "Spasatel Vasily Bekh, a tug of the Russian Black Sea Fleet, successfully demilitarized by the @UA_NAVY. The ship was transporting personnel, weapons and ammunition to the occupied Snake Island." Ukraine's Naval Command said the Russian tugboat had a Tor missile system on board.
