Neutron stars

Neutron stars are super dense remains of the core of a dead supergiant. They are the corpse of the majority of Type II supernova progenitors.

History
The first ever neutron star and pulsar discovered was listed as LGM-1 because of its extremely precise timing of its pulsing x-rays. It was later redesignated as PSR B1919+21 when astronomers actually found out what the object was. Magnetars were discovered more closely in the 2000s, mainly defined by the eruption of SGR 1806-20, the most powerful explosion ever measured in the galaxy. In 2081, the Pineapple Empire started experimenting with neutron stars, but was unable to produce any major results until the year 2136, where the Pineapple Empire managed to get a spacecraft in a 10km proximity with a neutron star. In 2150, the Pineapple Empire landed their first craft on a neutron star. Thanks to this massive success, the Pineapple Empire decided it would launch a massive space expansion program, which ended up with the creation of the Pineapple Space Fleet Operations Command (PSFOC).

Shortly after the PSFOC's creation, it started tampering with experiments on magnetars to try and force them to erupt, with a successful attempt in 2239. However, a massive accident in 2244 left several Paris-class frigates destroyed, 591,280 crew members and workers dead, and also damaged and forced the retirement of the Cepheus-class light cruiser, as the Cepheus-class was too badly damaged by the explosion to be of any use, and due to a global recession in 2238, it was retired. In 2268, the PSFOC decided to start finding ways to use gravity cannons to launch neutron stars far away to destroy enemy targets, which were already developed to launch supergiant and hypergiant stars. A prototype launcher was developed in secret and was on hold after the Illuminati-Pineapple Empire War, and 1/4 of the reparation funds from the Illuminati were used to hastily finish the project by 2302. In the wars against the Itanimulli and Karl, the neutron star launcher was tested multiple times against targets, and proved to be a massive success. It has not been used for over 5 years ever since.
