This includes things like "Time to target" and lots of other cool stuff:

But there's a lot of other cool stuff as well! Check out the full list below:
Bugs Fixed
- Sea state now changes gradually at normal 1× speed instead of becoming stuck until higher time compression is used.
- Bearings that round past 359° now wrap to 000° instead of displaying 360°.
- Submerged 1/3 and 2/3 engine-order speeds are now more accurate, based on the U.S. Navy's Current Doctrine for Submarines.
- Blind Hunter now remembers surfacing and visual-optics use when you save and reload during an encounter, preventing false unlocks.
- Submerged battery endurance now drops sharply at high speed, reflecting the limits of WWII lead-acid batteries: a fully charged Gato-class boat lasts about an hour at Full Ahead and 36 minutes at Flank Ahead, while economical-speed endurance remains unchanged.
- Periscope vertical reticles now use the intended fine subdivisions at both 1.5× and 6× magnification, while the fixed surface optics retain their original scale.
- Resizing map lines, angles, and compass circles now switches to a precision crosshair, while moving a whole annotation keeps the hand cursor.
- Improved Simplified Chinese text across the app.
- Added a very missing acknowledgment to my wife who would like everyone to know she doesn't want to hear the Mars theme ever again if possible.
Fun New Stuff
- Crew reports have had a full realism pass grounded in the surviving USS Sealion attack recordings “Attack on Battleship Kongo” and “Attack on oiler,” along with the U.S. Navy’s “Shipboard Calls and Commands” training recordings: the right station now reports torpedo, hydrophone, aircraft, depth, tube, and damage callouts with localized phrasing.
- Added "Time to target" callouts to crew reports, based on the TDC settings, called out every 30 seconds and at 20 and 10 seconds left.
- Settings now offers a persistent Imperial or Metric unit system, converting speeds, depths, ranges, map annotations, sensor contacts, TDC readouts, and campaign mission distances across tactical displays.
- Made the Damage Control station be a lot prettier, with an at-a-glance engineering assessment, hull and flooding meters, sink-rate status, and an approximate repair estimate.
- I gave dialogs, panels, popovers, alerts, and other transient UI smoother appearing and fading transitions, making the interface easier to visually follow.
- Heading and depth dials now preview the value under the pointer with a gray readout and guide before you commit the command.
- Reviewed and improved the Learning Hub and translated all 31 articles into every supported language.
- The Select Tool now supports a configurable hold shortcut for placing timestamped map points, with Alt assigned by default.
