The US Navy has awarded BAE Systems a $50 million contract option to upgrade four additional Mk 45 Naval Guns on guided missile destroyers.

According to a press release, the option was exercised under an initial 2015 award, brings the full value of the contract to $130 million for a total of 10 modernised gun systems.

Key updates to the Mod 4 configuration include a mechanically strengthened gun mount and a completely digitized control system. The stronger mount allows the gun to achieve 50 percent higher firing energy, and the new digital control system provides significantly more computing power while utilizing a user interface similar to that of a smartphone.

These enhancements enable the seamless integration of targeting and fire control data, such as GPS, positioning the Mk 45 to fire precision guided munitions at unprecedented ranges.

Joseph Senftle, vice president and general manager of Weapon Systems at BAE Systems said:

“The proliferation of high-volume, low-cost threats is driving the need for multi-mission, cost-effective precision fire from naval guns like the Mk 45.

As a leader in large-caliber naval guns and precision guided munitions, our team is committed to developing reliable and affordable technology that adapts faster and reaches farther than ever before.”

BAE say:

“The updated Mk 45 guns are expected to remain in service for decades to come, making the cost-effective Mod 4 conversion and the continued development of advanced munitions — such as the Hyper Velocity Projectile and Standard Guided Projectile — essential components of future surface warfare.

Work on the Mk 45 Mod 4 conversions will be performed at the BAE Systems’ facility in Louisville, Kentucky, with support from its facility in Minneapolis, Minnesota. Delivery of the first upgraded gun will take place in late 2017 with the last delivery scheduled for 2020.”

BAE Systems has designed, produced, and supported Mk 45 Mods 0-4 for more than 40 years.

Interesting about the guided long range shells. Type 26 is up for this gun I think.
