Here's a general loadout suggestion for the Mamba that might be suitable for infiltration missions:

Core Internal Modules:

• Power Plant: A-rated for improved power capacity.
• Thrusters: A-rated for better maneuverability.
• Frame Shift Drive: A-rated for improved jump range.

Optional Internal Modules:

• Sensors: D-rated for reduced mass and power usage.
• Life Support: D-rated for reduced mass.
• Power Distributor: A-rated for improved energy management.

Hardpoints:

• Consider using energy weapons such as Pulse Lasers or Burst Lasers to minimize the risk of detection due to projectile travel.
• Silent Running modules may be beneficial to reduce heat emissions, but this comes at the cost of increased module damage and limited functionality.

Utility Mounts:

Equip modules such as Chaff Launchers and Heat Sink Launchers to help evade enemy scans and manage your ship's heat signature.

Core Internal Modules (Optional):

• Install a Fuel Scoop if the missions require long-distance travel.
• Install a Detailed Surface Scanner to scan targets for additional information.

Optional Internal Modules (Optional):

• Consider adding a Shield Cell Bank for emergency shield regeneration if you get detected. Install a Frame Shift Wake Scanner for mission-related activities.

Engineer Upgrades:

• Visit engineers to upgrade key modules like the Frame Shift Drive, thrusters, and sensors for improved performance.

Remember, the success of an infiltration mission also depends on your piloting skills and situational awareness. Always check for the latest updates and community discussions for the most effective loadouts in the current game version. Additionally, be sure to adapt your loadout based on the specific requirements of the infiltration missions you undertake.
