The LSC Tab(the tab at the bottom left of the construction UI) can be unlocked once you have completed a certain quest (which is scrap 4 pieces of equipment that comes after once you have completed the sendai sister quest and the successfully modernize 4 times)

At low levels, you would have a hard time crafting so the best way to get one is to build certain ships. The resources that you need to can be collected comes from expedition (the green button at the right part of the sortie UI, which you can abuse all the time). Dev mats can be collected via expedition (not reliable) or via quests.
