Laid down in 1916-18. The three ship Hannibal class followed on the eight gun improvement line that the Greenland battleships had been following. The Dido class had been 8x16", therefore the next logical step was to go to battleships with 8x18". Doesn't sound much, but the jump in size of everything fitted to the ship was huge. Bigger guns, more armour, larger machinery plant to attain the same speed as the Dido's. The ships would be over 100 feet longer and nearly 10 feet more beam. This added up to a 12,000 ton jump in size. These ships also introduced the Greenlandian Navy to the Coventry Works 5.5" secondary armament gun. This would be used on many future ships, including cruisers, which is what the gun was originally designed for, two Greek light cruisers. The Hannibal was completed in 1921 but its two sister ships were caught in the Washington Treaty and were not allowed to be completed. The two ships were allowed to be repurposed as aircraft carriers the same way the US and Japan had done with the large ships that the Washington Treaty allowed them to convert.
Greenland already had two ships being converted to aircraft carriers, the Hadad and Manuzi. Those ships were already two and a half years into their conversions, and a lot of what was good and bad had been sorted out. The Greenlandian Navy received a lot of information from the USN and Royal Navy on the work being trialled on their ships. This allowed the Shacar and Molloch to be converted to the highest specifications possible.
Because of the massive size of the ships, it was felt that a double storey hangar could be fitted. The upper hangar at 18 feet and the lower hangar at 20 feet. The two ships would follow the US Lexington type with enclosed bow, rather than the Japanese ships with their multiple launching capability from several run off decks forward. The Royal Navy trialled this on the Furious but went to the enclosed bow for the Courageous and Glorious.
The Greenland designs would also follow the USN layout of main armament, with the turrets being mounted fore and aft of the bridge superstructure. Where the USN and Japanese mounted 8" guns (the maximum size allowed by the Washington Treaty) the Greenlandian ships would have the same twin 5.5" turrets as used as secondary armament on the Gisco class battlecruisers. While this looked good on paper, the actuality had air flight operations being interrupted any time the 5.5" needed to be fired to port. This would be fixed over time as dual purpose guns were fitted and the low angle turrets replaced with AA mountings.
