As part of the seven-year programme, the company provided major modification and overhaul work to convert 13 Mk8 guns to the required specifications.

Babcock Equipment Solutions managing director John Stratton said: "We are delighted to have successfully delivered the full Mk8 Mod1 upgrade programme on-time and in-budget, further underlining our strong capability in the field of weapon support and upgrade for the MoD and Royal Navy."

Featuring computer-based test and diagnostics system, the Mk8 Mod1 gun is fitted with new electric drives to enhance safety and power consumption efficiency, while reducing overall weight and below-deck space requirements.
