» 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 70 nmi (81 mi; 130 km) to
167.5 nmi (192.8 mi; 310.2 km), along with a new lighter 300 lb (140 kg)
warhead and a more fuel-efficient engine with electronic fuel controls.
Boeing offered the missile as the U.S. Navy’s 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 NSM 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.»

Προφανώς η αναβάθμιση στο απλό block II+, που αφορά μόνο τα ηλεκτρονικά και όχι αλλαγή γόμωσης και προωθητικού σκεύους θα είναι ακόμη φθηνότερη, ίσως και στα μισά. Σε κάθε περίπτωση μας συμφέρει η αναβάθμιση αντί της αγοράς νέων Εxocet, αφού στην τιμή ενός Exocet μπορούμε να έχουμε 3-6 πλήρως αναβαθμισμένους, εξίσου σύγχρονους Ηarpoon. Τα λεφτά που περισσεύουν καλύτερα να πάνε σε καινούργιους πολυηχητικούς Perseus, που θα είναι διαθέσιμοι από το 2030 και μετά.
