Summary: Sweden's Saab recently completed significant mid-life upgrades on HMS Halland, the last Gotland-class submarine to receive enhancements, improving stealth, navigation, and combat systems.

The training marks a milestone in an agreement that calls on the U.S. to send submarines to Australia in the 2030s and 2040s.

These 51m-long subs were built for the Royal Swedish Navy in 1968. The first of the four Challenger-class submarines was launched in 1997 in Sweden. RSN personnel trained with the Royal Swedish Navy.
