Welcome Oleif!

My best guess is that you will stay with your brand new VIIC for at least 15 missions before upgrading to an IX. Make every of these missions count and gather a lot of renown. Then go to a IX-B and when you hit mission ~40-45 an XXI. But you will need 30.000 renown for that.

As far as individual upgrades, my view regarding their significance (in order):

- Radar Detector
- Hull coating
- Countermeasures (Bold 1, 2 etc.)
- Snorkel
- Radar coating
- Conning tower with heavy flak
- Homing torpedoes
- Engine upgrade
- Sonar
- Radar
- Battery upgrade
- Other todpedo types

Have fun!
