To speak on a meta level, one of the key reasons space fighters feature so prominently in the Ticonderoga series is due to the strong influence of the Wing Commander series on the story. Also, the stakes don’t feel quite as high for remote drone operators as for pilots physically in the cockpit. Also, the deep impression in the popular consciousness of the heroic dogfighting of the two world wars have been perpetuated through major works of science fiction and will continue to be a staple even as technology seems to be bringing the classic concept of dogfighting more and more into obsolescence. However, rather than simply handwave all this, I do try to make some in-universe justification for it all, which I will explain below.
Before the start of the Sheol War, superlight spacecraft (under 50m in length and 300t in weight) were mostly limited to unmanned drones and the occasional custom curiosity. A large part of the reason for this was because the Schauer Fusion Propulsion System, which was the cornerstone of all space travel, could not safely be downscaled any further. At that time, space operations mostly fell under the Navy’s jurisdiction and the prevailing notion was that in any combat situation, the typical patrol escort was the smallest type spacecraft that would be needed. However, even before the Sheolites were identified as such, their small maneuverable craft were proving quite effective. While some in the Navy advocated warships with denser weapons arrays to deliver an impenetrable wall of interlocking fire, the risk of collateral damage was seen as too great, though the fifth generation warships developed during the war were much more heavily armed than their predecessors. Both the Air Force and Naval Aviation saw an opportunity to seize a larger role in the coming conflict and argued in favor of fighting fire with fire with superlight spacecraft.
The superlights would not have been possible without the development of the of the SFPS Mk.VId, a downscaled version of the SFPS previously thought impossible. Though much improved over previous attempts to downscale the SFPS design, the VId was nevertheless unstable and the containment could easily be broke with relatively little damage. Safety systems were put in place to shut down the reactor upon taking damage, but this did not always work and when it did, the superlight was left dead in the water and easy prey for the enemy.
While G-diffuser systems were installed to make the cockpit survivable for a human pilot, the theoretical limits of human reaction time were strained even at the reduced engagement velocity of 100kps. Given these and other concerns, there were many voices who argued against manned superlights, instead advocating either fully independent combat AIs or at least remote operators. The use of independent AI was always politically untenable in the Earth Union. For whatever flaws a human being may have, there is at least clearer accountability in the event something goes wrong. (A discussion on the complex debate on the role of AI in Earth Union society is best saved for another time.) While remote operators at least kept a human in the loop, there were concerns that the connection could be severed or even hijacked by the enemy. (Later review would confirm that the detractors overestimated the Sheolites’ electronic warfare capabilities.) In the end, the advocates of manned superlights won out.
Now that the plan to go forward with manned superlights was going forward, both the crafts themselves and the warships to carry them were being developed alongside the training of the pilots who would fly them. For instance, both Leia Han and Stalinslav Zhukov (who you would better know as Pride of the Seven Deadly Sins) were among the first midshipmen to be trained as pilots for spaceborne carrier operations. In addition, pilots from the terrestrial aviation communities and the pilots of light spacecraft adapted their skills to operate the new superlights. Casualty rates in training were high and even higher in combat, but those who survived helped refine the warfighting doctrine for superlights. Combined with technological advancement, the second generation of pilots (represented by people like Matt and Lydia) were able to gain an advantage over the Sheolites and by the third generation that emerged by the war’s end, clear superiority on the Union side was established.
Following the postwar drawdown of forces, the expense of manned superlights became harder to justify in the changing political climate and worsening economic situation. By the time of the War of the Colonies, the Union had almost completely shifted to remote operators and only when rebel forces succeeded in realizing the concerns of the opponents of remote operators did manned superlights make a resurgence, but by that point it was a race against time to relearn what had already been well-established forty years earlier.
And that should do it for now. There are a number of technological brawls in Union military history and perhaps I’ll get into another in the near future. For my next commentary post, I may talk a little on the embarrassing origins of the Ticonderoga series and some of the early weirdness that was cut before the story saw the light of day. Stay tuned.
