You will need at least 4 for quest and preferably, you want at least 4 of them available for use at all times:
 * 2 is needed for quest F30 to get the.
 * Another 2 is needed for quest F45 to get the.
 * 1 is for your fleet use during sorties, if you want to increase your Contact rate and prevent Red-T.
 * Saiuns have 2 uses in LBAS. As Meomeongungu has stated, it can increase the flight distance of your other planes, but the other use is as a modifier to increase your air power during air defense. If fighter power becomes relevant in air defenses, a Saiun is almost always better than another fighter. Having 3 Saiuns available here ensures that you can use one for each LBAS.
