Build 1.3.1 | Naval Estimates - Free Naval Grand Strategy Wargame

What started as a bug hotfix gained some additional features along the way: a rework of costs, which now include design and tooling, improved burst and fragment handling, a new stern type and a review of transom stern drag, better quad mount sizing, single-masted ships and collision checks for the rigging, and a Post-Treaty option for 1928 that grows the yards and pits slightly. Plus, of course, a pile of bug fixes - geometry and balance both.

Old campaign saves and design files load fine. A campaign saved before this build asks to update its tech levels on load.

Some saved designs may shift slightly: quad turrets, build times and costs, upkeep, and some fuel consumption and drag - the last especially on transom stern designs.

Additions

Transom (Canoe) stern: the flat-cut elliptical of the G3, Lion and Vanguard classes
Design Time and Tooling Time costs are shown for both guns and turrets
Saved mount summary cards can be viewed the same way gun summary cards can
Hover tooltips for torpedo deck mounts and tube rooms in the 2D view, and the magazine tooltip now shows its mount
The Summarize card reports the torpedo armament
Single-mast wireless rigs are legal, and the rigging run is checked for fouling funnel tops, superstructure roofs and gun mounts at full elevation
Post-Treaty Yard Growth: a 1928 campaign can opt into a slightly expanded infrastructure table
A Frags selection (20 to 100) for penetration mode in 3D, and Shell Paths and Shell Markers can be hidden in Salvo mode - the selected shell still shows them
The turret designer’s ring states the hull beam the mount requires

Fixes

The Boiler Overhead slider had no effect on weight or cost
Deck torpedo mounts, gun mounts and casemates on a lowered quarterdeck floated at main-deck height in the drawing and the 3D view
A ship design could lose values on a cold load or import: the deck slope snapped to the armour scheme’s default, a funnel’s rake drifted further on every reload, and an internal belt scheme switched itself off
A raised forecastle met its deck at a visible corner
A lowered quarterdeck puckered the bow flare, and a deckhouse on its slab showed a see-through gap at the corner
Mast feet and staffs on an extended forecastle or quarterdeck stood a deck step too low
A casemate’s roof was judged at its face thickness by the penetration probe when a shell plunged through the deck onto it
Salvo mode splashes were sized off the gun’s bore whatever hit the water; heavy fragments made no splash, and a phantom splash and a ghost line were drawn past the burst
One magazine of a mirrored secondary pair could be reported unable to stow its stock with room free on its own side
A mount over a deep torpedo-defence system was refused hull support it had; structural support now reads the hull’s own buffer line
A superfiring mount could show a false barrel-collision warning while safely firing over its sister
The curve for allowed ammunition weight for semi-fixed rounds was adjusted
Typing a turret face thickness under Auto Scaling snapped the figure to the material floor mid-keystroke
The cavitation triangle lit on a ship at 0% loss
Battery hoist head rooms raised a false “Head exposed” on large capitals
The ship cost’s + marker appeared when it should not have
A transom stern’s cut face shaded into the hull side in 3D
The Danger Space and Pattern range stepped in metres under imperial units

Balance

Costs re-anchored, and in a named unit: one budget unit is $100 of constant 1910 dollars. A lined gun shows its reline cost, and a reserve set of barrels shows under the ship’s total
Upkeep ages on one smooth curve at each design’s own pace, with expected cost at 5, 10 and 20 years shown
Build times reviewed, along with Design and Tooling times for gun and turret designs
Double reduction reworked, as it was not providing benefits
Screws in each other’s wash suffer penalties: three- and four-shaft ships lose power where the screws crowd, a severe overlap is an error and a lighter one a warning
The transom stern drag ladder is re-anchored - it was using a surface area several times too large
Quad turret sizing reviewed and fitted better to historical examples
Gunhouse face overhang reduced
Base-ring mount magazines may slide inboard like a pedestal’s, from below the working chamber
An internal torpedo room counts as an above-water installation only when its tube clears the waterline by a full diameter
Tech tables rebuilt for each start date
The fragment and bursting models sample their distributions properly instead of clustering around the midpoint

Other

Salvo mode rows say what the struck plate did - pierced, holed, held or glanced, a deeper plate that held, where the shell burst, or why it did not
The Danger Space and Pattern range is typed rather than dragged, with the striking velocity and impact angle beside it

Costs, upkeep and quad turrets all moved in this one - if a saved design comes back looking wrong, the Discord is the place.
