Gravity and drag losses of some launch vehicles
To get a better view of the settings of different vehicles here is the numbers:
| Vehicle | Gravity Loss, m/s | Drag Loss, m/s |
| Ariane A-44L | 1576 | 135 |
| Atlas I | 1395 | 110 |
| Delta 7925 | 1150 | 136 |
| Shuttle | 1222 | 107 |
| Saturn V | 1534 | 40 |
| Titan IV/Centaur | 1442 | 156 |
Ariane A-44L: Gravity Loss: 1576 m/s Drag Loss: 135 m/s
Atlas I: Gravity Loss: 1395 m/s Drag Loss: 110 m/s
Delta 7925: Gravity Loss: 1150 m/s Drag Loss: 136 m/s
Shuttle: Gravity Loss: 1222 m/s Drag Loss: 107 m/s
Saturn V: Gravity Loss: 1534 m/s Drag Loss: 40 m/s (!!)
Titan IV/Centaur: Gravity Loss: 1442 m/s Drag Loss: 156 m/s
