The Halifax B Mk IIIa is a British bomber. It was introduced in Update 1.59 "Flaming Arrows".

The Halifax is an interesting member of the British bomber line. It is the first true British heavy bomber, a big change from its predecessors, which are all either flying boats, medium, or light bombers. With the transition to heavy bombers, comes a change in tactics. The Halifax will outclass almost every rank 2 and 3 bombers in terms of payload. It will also generally beat every same battle-rated bomber in the payload department as well. However, being a heavy bomber has its drawbacks. Compared to nearly all previous British bombers, this one is slower and has a noticeably slow climb rate. While the payload upgrade is nice, the Halifax is not very durable. Worse, the Halifax lacks effective defensive weapons, a flaw of nearly all British bombers. The main priority, as a result, should be targeting bases and avoiding opposing pilots as much as possible. Use high altitude and less direct travel routes to get to your targets. If you are engaged, your defensive guns can save you, but they are not very reliable. In addition, this bomber does not have any ventral turrets, leaving a massive defensive gap directly under the aircraft. You also only have one singular machine gun able to cover the fore-lower approach to your aircraft and little in the way of armour plating for the pilot other than a steel bulkhead that won't protect against cannon shells or rifle-calibre bullets well. However, if you can keep safe and deliver your payload, you will find this to be a very effective bomber.
