How would an imperial Roman legion fare in early medieval Europe?
A fully equipped legion at the height of imperial strength would probably remain effective, partly because it brings a substantial body of troops.

Andromeda and the loss of warship-building capacity
Austria-Hungary's collapse offers an analogy for lost warship-building capacity, challenged by the resources of surviving powers in Andromeda.
A wider Dark Ages and the Saxon burh
A Western European Dark Ages label can obscure Byzantium, the Arabic world, China, and large Anglo-Saxon programs of fortified urban construction.
Did battleship-building capacity vanish by the 1960s?
Counting new battleships understates how Britain, the United States, France, and the Soviet Union redirected large-warship capacity toward carriers, modernization, and large-cruiser programs.
Did castles stop the Mongols?
A strong castle was not an absolute barrier because Mongol forces could contain it, starve it, and continue ravaging the surrounding territory.
Compact armored warship or large space cruiser?
Combat favors the smaller armored target, while long-range operations favor volume for stores and endurance.
Which countries built full-size carriers after 1970?
The post-1970 comparison identifies a short list of carrier-building states and explicitly includes Britain's Queen Elizabeth class.
Did European knights stop the Mongols in Hungary?
An interpretation of the Mongol withdrawal gives greater weight to succession politics than to resistance from European knights.
Do Cavour and Príncipe de Asturias count as carriers?
Cavour receives an affirmative classification as a carrier, with a more tentative answer for Príncipe de Asturias.
Using the corvus to bring Roman infantry into a sea fight
The corvus brings opposing ships together so Roman infantry can fight Carthaginian crews at close quarters.

A viewer counters the earlier succession argument with examples of Hungarian resistance to Mongol invasion.
Why Finality cannot wait for reinforcements
An isolated reconnaissance ship faces an enemy destroyer while faster-than-light messages and reinforcements still take hours or days.

Anthony James stages a small warship's escape around a hostile planet through sensors, missiles, decoys, point defence, and heat limits.
Why Starfleet needs fighters and uncrewed systems
Discovery's uncrewed ships and Deep Space Nine's fighter wings add variety to Starfleet's recurring phaser-and-torpedo weapons mix.
No Honor in Death and command of a crippled battleship
A wounded executive officer takes command of Victoria Regina after the captain and combat information center are destroyed.
Victoria Regina's final maneuver against the cruiser
A damaged battleship uses its remaining weapons, a roll and a sudden diving attack to surprise a cruiser expecting conventional maneuvers.
Surviving Victoria Regina and reliving the battle
The battle's aftermath follows a surviving officer through recurring nightmares, repeated ship losses and the death of a trusted captain.
Transporters delivering nuclear weapons
Odyssey One supplies a fictional example of teleporting nuclear weapons directly inside opposing ships.
Why Star Wars fleets underuse smart weapons and turrets
Fleets with sophisticated droid intelligence make poor use of it when their weapons lack comparable guidance and their guns fire through fixed hull openings.
F-35 reporting and access to engineering sources
A journalist's difficulty obtaining on-record answers about the F-35 explains the value placed on speaking with an engineer involved in the project.
Designing turret arcs for three-dimensional combat
The Manticore in Battlestar Galactica: Deadlock illustrates the cost of restricting a space warship's most useful guns to narrow firing arcs.
Why write about destroyers before cruisers?
Research gaps and the ships surrounding cruisers help explain the choice to write about destroyers, sloops and naval aviation.
Could Discovery's repair drones repel boarders?
Discovery's repair drones suggest a possible defensive use, compared with Farscape's maintenance robots.
The F-35 as a networked strike aircraft
A favorable assessment of the F-35 emphasizes its connected strike role and compares that role with the Sea Harrier.
Why write another history of Q-ships?
A proposed Q-ship book would connect detailed ship history with the strategy, decisions and wartime employment behind the vessels.
A revised Manticore layout with turrets and point defence
A proposed Manticore redesign combines four turrets with forward missile launchers and point-defence lasers around the hull.
The Fairey Seafox at the River Plate
The Seafox's scouting and observation work gave a small cruiser floatplane an outsized role in the Battle of the River Plate.
Designing a reconnaissance floatplane for light cruisers
Air Ministry requirements shaped the Seafox as a two-seat, catapult-launched reconnaissance aircraft for Royal Navy light cruisers.
Why cruiser floatplanes disappeared from wartime fleets
Mediterranean air cover, recovery hazards, and the growth of carrier aviation reduced the wartime value of cruiser-launched floatplanes.
The Fulmar and Firefly followed separate paths from P.4/34
The Fulmar and Firefly shared a design ancestry, but the Firefly was not simply a later Fulmar because Fairey's development chain had been broken.
The Albacore traded Swordfish simplicity for modern equipment
The Albacore added an enclosed cockpit, heating, hydraulic flaps, and other comforts but could not match the Swordfish's dependable Pegasus engine.
The institutional gap behind Albacore procurement
The Air Ministry-Admiralty system separated naval aviators from aircraft producers and weakened the institutional knowledge behind procurement decisions.
Landing-speed limits and the naval-aircraft power gap
Low carrier-landing speeds pushed designs toward biplanes while rising equipment weight outpaced the power of many mid-generation engines.
The Firefly as Fairey's heavy naval fighter ideal
The Griffon-powered, cannon-armed Firefly represents the heavily equipped two-seat naval fighter that Fairey's earlier Fulmar could not become.
How the Fulmar stopgap became a wartime commitment
War prolonged the Fulmar's temporary role while engine competition, logistics, and airframe weight limited the Royal Navy's alternatives.
Fulmar armament and layered fleet air defense
A heavy naval fighter needed cannon fire to break up incoming formations before they reached the fleet's anti-aircraft screen.
The Gordon and Hendon show Fairey's early-1930s transition
Compare the Fairey Gordon light bomber with the Hendon heavy-bomber prototype and see how rapidly British aircraft design was changing.
