Which fixed wing aircraft is equipped with 30mm, 105mm, and small diameter bombs?

The AC-130J is the correct answer because it is specifically designed for close air support, intelligence, surveillance, and reconnaissance missions. This aircraft is equipped with advanced weaponry including a 30mm cannon, a 105mm howitzer, and the capability to deploy small diameter bombs, which makes it highly versatile for engaging ground targets.

The combination of its armament allows the AC-130J to execute precision strikes while maintaining a unique ability to provide sustained fire support in various combat environments. It is optimal for engaging targets in a more controlled manner, often in support of ground forces, showcasing its role in modern warfare.

In contrast, the other aircraft, while formidable in their own right, are specialized for different mission profiles. For instance, the F-16 and F/A-18 are primarily multirole fighters that focus on air-to-air combat and air-to-ground attacks but do not match the AC-130J in terms of sustained on-station firepower with heavy armaments like the 105mm howitzer. The B-1B, although it does carry larger ordnance, does not feature the same configuration of weapons or capabilities as the AC-130J, focusing instead on high-speed missions and strategic bombing rather than
