In Rogue Trader's Battlefield Koronus book, page 36, it indicates that "a Landing Bay comes equipped with one squadron per point of strength". While it indicates clearly what a squadron can entail, it is unclear on what a landing bay's strength is. The chart on page 41 only indicates Power, Space and SP (which is Ship Points, yes?). How do you determine the Strength of a landing bay?

Page 35 of the Battlefleet Koronus book has your answer.
Table 1-9: starship weapons on page 35 is a table of different starship weapons, including landing bays. It includes the strength value of every weapon, as well as other relevant stats.
Specifically for landing bays, all landing bays have a strength of 2, except for the Jovian-pattern Escort Bay that has a strength of 1.
The table on page 41 also includes the landing bays, but has less information than table 1-9.
