Harpoon replacement

" “There is work ongoing to look at options for longer extension in service,”"

If you are pointing at the US Navy - well they had their 'gulp' moment regarding the threat posed by the Soviet aircraft at the turn of the '70s. Phalanx CIWS prototypes were being evaluated on land by 1972 and afloat by '73. By the Falklands the system had been in full production for a number of years. Their leap forward in integrated combat systems and associated radars & missiles was arguably even more significant.

Meanwhile we were producing Type 42s.
One of my University lecturers (ex RN) did say that the Type 42 design was criticised before they entered service - however:

Regarding Phalanx, I think you have your dates mixed up.

The prototype Phalanx was installed aboard USS KING (DLG-10/DDG-41) in 1973 for evaluation. Another prototype CIWS was used in tests conducted aboard ex-USS ALFRED A. CUNNINGHAM (DD-752). Several different kinds of missiles were fired at CUNNINGHAM; all were shot down. Full operational and evaluation trials were performed aboard USS BIGELOW (DD-942) in 1977. The evaluations included tests with high levels of jamming noise during which the unit succeeded in distinguishing small missile-like targets against nearby islands.Phalanx met and exceeded all maintenance and reliability requirements. The first production units of Phalanx were installed aboard USS CORAL SEA (CV-43) in 1980. Installation aboard noncombatant ships began in 1984.
