The Texas Ranger Abilene-class starships were fully upgraded to the best of our technology before The War. They received full Peloran tech during that conflict and further modifications have improved their performance since War’s End. They now boast the very best hyperdrive and inertial compensator technologies from both the Peloran and Texas technological trees. Modern engines generate far more thrust than the old, ancient engines of the pre-gravtech era, while maintaining the same silhouette as older Abilenes. They are small ships with big engines that can accelerate far faster than most other ships. And their Peloran hyperdrives can go deeper into hyperspace, where that speed advantage is further reinforced. Unofficial estimates suggest they can travel 150% faster than a front line American Navy squadron. The Texas Rangers do not comment on their actual top speed, maintaining it as an official secret of the Republic of Texas. But they are one of the fastest ships in space.
