Yukari saw the ETA count to evaluate the distance from Miharu's to its target, the Obakemono, bogged down around 20 seconds, stall and then slowly start increasing! She understood why too.
The Obakemono's navigator apparently kicked in the Ayame cruiser's sublight engines in reverse in an attempt to do a 'gravity whip' maneuver. Essentially, they were riding the planet's gravity well in a declining orbit, using just enough thruster power to keep away from the atmosphere while both picking up speed and blocking line-of-sight with Miharu with the cover provided by the planet.
It was the sort of maneuver Yukari had kept in her mental bag of tricks back when she was being the navigator for freighters. Seeing the ponderous Ayame cruiser manage it so gracefully spoke highly of the skill of the person whom was at the helm. As things were, Miharu would not catch up before the Obakemono's would manage to reach full charge with its Legacy cannon, deploy its weapon pods and release its escort ships.
It was clear that once the escort ships would be released that the situation would turn very sour for them. Not only would Miharu be staring down 9 ships, but those ships would have sufficient asset to counter the interdiction field and allow the use of the Legacy cannon.
Kotori's lips curled as she glared at the display, not having Yukari's insight in the maneuver, but understanding that her original plan of attack had been upset in one clever maneuver from the person at the Obakemono's helm. It was just delaying maneuver, but stalling so considerably improved the survival chances of the Obakemono's squadron.
I thought they would have tried to be aggressive for the sake of protecting their ground base... Kotori nibbled at her lower lip a moment and then nodded grudgingly at the 'Epsilon 1' icon, like a fencer acknowledging a hit. But I suppose the other commander felt the safety of her ship was more important than the base below.
"Plan to attack Epsilon 1 is aborted," Kotori announced on the intercom while she disconnected power conduits and electronic linkup between Miharu and Hoshi - obvious warning that they would separate imminently. "Hoshi, you shall proceed as planned to the planet. Do your part of the mission; we'll improvise on our side."
As if on cue with her last word, locking clamps disengaged and Hoshi was released, pushed away for good measure with the help of graviton beams. The Fox and Cougar shuttles were still within the confines of its launchbays - it would be up to Nyton to order them around. Miharu's ventral hatches ejected the two fightercraft, with the Uriko and Ryuseii quickly spinning around to follow.
"Hold fire and disarm current torpedo loadout for two front-facing AS-7 Anti-Matter warheads," Kotori ordered Miyoko. "Get me a target lock on Epsilon 1 as soon as you can."
The AS-7 AM were pretty much the strongest type of warhead Miharu carried for purposes of dealing damage to an enemy ship, but asking these to be reloaded was tantamount to Kotori saying she had no better idea for the moment.
She turned to Yukari. "Shosa, disengage the limiter on our gravimetric engines. I need us to reach .9c and catch up with them. Make as sharp a turn as you can around the planet."
Most KFY-made ships could go in overdrive and double their sublight speed. Miharu could handily do so as well, but seeing its engines were experimental equipment, it was possible to remove the limiter and allow, for roughly half-a-minute, to triple the ship's STL speed - more than that would risk the engines overheating. It was risky: pushing the envelope was like begging the engines to malfunction and efven with Miharu's vaunted maneuverability, making a tight turn at nearly the speed of light and around the planet would be difficult even for a veteran nekovalkyrja navigator with a SPINE interface connection.
