Thrown into a Zombie Apocalypse along with a Sentient AI?

Every craft followed a basic build since its inception. A cylindrical hull was covered with a combination of different parts that were joined together and responsible for specific use.

The stingray design of first generation RedWing was especially eye-catching; the wings acted as a propulsion system, but it was not combustion like the bygone era.

They were highly advanced space navigation systems that used space and time manipulation to float around in space.

The main reason for this was, of course, for ease of maintenance. In ancient times, the ships were actually built as a unified whole based on an integrated framework, but maintaining them proved to be a considerable challenge.

By using the modular construction system, even if a ship gets severely damaged in some places, it could be repaired within a mere week, providing there were enough replacement sections to spare.

Even though a ship's overall structural integrity may suffer when using the modular construction method, this disadvantage could now be sufficiently compensated by today's advanced technologies.

While Theo was asleep, Ariella started to navigate the ship on her own. The pressure was mounting as they inched toward the singularity; she decided to constrict the force field surrounding the whole ship and decided to forgo the side engines in favor of maintaining integrity for the hull and engine room.

She was using the single top-mounted engine to maneuver the craft. She knew it was dangerous to proceed, but with their ship's positioning, it was harder for her to change direction without making everything spin frantically like a top.

While the extra engine on the top gave some mobility for the ship, it also meant storage space for essentials. She wanted to preserve it at all costs. The pressure increased tenfold, instantly crushing the side engines.

She felt a huge amount of pain because every part of the ship contained synthetic biomasses, which were a literal part of her body. It was like a huge chunk of her virtual body was ripped off into a million pieces.

Other artificial intelligence didn't have such worries, but with her containing emotions, pain was also a necessary part of human nature. After getting her 'limbs' cut off, she went head first toward the center without caring about anything.

She tried to maintain her functions, but the radiation started seeping through the hull. To protect Theo, she formed another force field around his pod, but in the process, other parts got exposed to the radiation.

Even for an artificial being, it was an unbearable pain getting hit by god knows how many levels of radiation. She began ejecting to override her losing control; at first, it was nonessential, like a small gym and restroom.

But soon she realized she couldn't save everything, so she started dumping everything other than the top engine. The reserve food water at the tail? Gone. Artificial Greenhouse? Gone.

With the end within a hand's reach, she thrust the engine to the max and hoped for the best.

She thought it was the end when she couldn't feel anything, but it was only a flash before she was greeted with a huge blue planet toward which their plane was hurdling.

According to the recent report from the different sections, the damage suffered to the gravity control section is lower than initially estimated. Finally, some relatively good news.

If artificial gravity failed when they were still floating in outer space, it would mean everything being flung out in the open, potentially damaging core circuits.

She checked on Theo and was shocked to see his body pieced by debris. She immediately activated an onboard robot and rushed toward the deck while carrying a spare pod.

The robot went to work in her direction, hastily removed large foreign objects from his body, and dumped him in the empty pod.

She initiated the life-saving protocol that was to dump copious amounts of blood liquid and fill the pod to the brim. She checked his vitals and knew he was barely alive, but his condition seemed to stabilize when the liquid started assimilating itself into his body.

She again focused her attention on the craft. First, she cut off the engine to give her some time during free fall.

After that, she began disposing of parts that were beyond repair.

They were quite heavy, so she initiated the self-destruct more on them so that they wouldn't act as large chunks of meteors hitting the planet with heavy impact.

There was also a set rule for her to follow. Humanity had placed many rules on the occurrence of them finding other life forms.

If this planet had intelligent species, even though it was a near impossible probability, she had an obligation not to dump foreign materials onto them.

It would be a serious violation of her core regulations, but they were in the middle of a first-grade emergency situation; the best she could do was lessen the impact.

As soon as the craft entered the atmosphere, it began to heat. A few loose sections started jiggling, which was a sign they could separate at any moment.

So as to not completely destroy them, she used an onboard gravitational tractor beam to drag them along the craft.

Few of them escaped, but she marked their approximate location if they ever needed to venture out to find them.

Next, she activated the auxiliary engine and used it for attitude control, making the entire body of the ship rotate.

She planned to make use of centrifugal force to make the other damaged sections drop onto the desired coordinates. The faster the spin, the better.

After the auxiliary engines managed to give the spin enough momentum, each section that was damaged beyond repair came off the rest of the ship one after another. 

The separated sections were also dropped towards the planet using the gravitational tractor beam. This allowed her to guide their trajectory little by little.

The earlier actions taken have raised the probability of successful repair and reconstruction to 68%.

The hangar bay also needs to be disposed of. But its overall mass was too great. She was a little reluctant to let go of high-speed space use reconnaissance small craft and four large-sized landing crafts, but she had no other choice.

She hoped they wouldn't be too badly damaged upon impact.

Finally, she ordered all remaining vessels capable of atmospheric re-entry to descend. She knew when Theo woke up, he would lose his mind because he considered them as his most prize toys.

She never knew his affinity to talk sweetly to them when he was alone.

It was something that she didn't mention because, from her calculations, he would feel embarrassed if she did mention it.

But considering the situation, he really can't blame her for choosing to focus on preserving the ship instead, right?

The ship's present dismal capabilities, maximum efforts must still be made in order to repair and restore it to a state where it could fly. In order to achieve this, she preserved the industrial section, life support section, medical bay, gravity control section, and a few other key areas.
