Notes: No Shields or photon torpedoes. Shields currently in development, hopefully photon torpedoes also coming in the future.

Romulan warbird is bigger and a bit slower than the Enterprise and may take longer to respond. However, it possesses greater range in its phaser array.

Space flight tips:
Ships are currently in orbit around planet. Real world orbital mechanics apply.

To increase apoapsis altitude: Thrust prograde at periapsis.
To increase periapsis altitude: Thrust prograde at apoapsis.
To decrease apoapsis altitude: Thrust retrograde at periapsis.
To decrease periapsis altitude: Thrust retrograde at apoapsis.

Don't crash into the planets surface. Don't shoot yourself with your own phaser array.
Enjoy!
