"Luda" mid-life upgrade (051DT)

The PLAN has performed mid-life upgrades on several of its "Luda" class destroyers. Some ships have been upgraded with a new ZKJ-4A-3 combat data system (C3I), Crotale/HQ-7 SAM, HY-1/HY-2 missiles replaced by 16 YJ-83 (C-803) anti-ship missiles, and manual AA guns replaced by Type 76A dual-37 mm automatic AA guns. The upgraded ships are sometimes referred to as the Type 051DT. At least 2 ships (109 & 110) are reported to have been upgraded to the Type 051DT standard, with more expected to follow.
