In 1890, the navy commissioned its most powerful warship yet. The French-built
San Ignacio coastal defense ship was a radical departure from previous warships in Lisenian service. The one-off vessel resembled a large river monitor, clad in heavy armor, bristling with casemated 6-inch guns and designed around a single massive Canet gun, one of the most powerful pieces of naval ordnance at the time. The San Ignacio was the ultimate expression of the ideal Jeune École warship as envisioned by the French-educated sections of the naval staff. By this time, a good portion of the naval officers had received training abroad in the United States, and came to regard the small but heavily armed coastal cruisers and the
San Ignacio as white elephants. Unfortunately for the
San Ignacio, its first few years in service did much to prove its critics correct.
The 12.6-inch gun was undeniably powerful and capable of crippling much larger ships, but serious problems were revealed during exercises. The sheer weight of the turret threatened the stability of the ship when aimed to either beam, which in turn reduced accuracy against distant targets. Reloading the hefty rounds, which weighed almost 900-lbs each, was incredibly difficult. Cramped conditions in the turret, crew exhaustion and magazine rooms combined with unreliable loading machinery made it impossible to match the manufacturer's claimed rate of fire. In practice, the Canet piece took almost to an hour to reload, which was simply unacceptable in combat. The weight of the gun and forward magazine also contributed to poor sea-keeping, the result being a very wet bow at the slightest hint of swells.
The San Ignacio was still faster and better protected than the previous coastal defense ships however, and the American-sourced 6-inch QF guns were regarded as excellent. These guns were in fact so well liked that arrangements were made to produce them locally at the naval arsenal, and several older ships received the 6-inch QF as part of their refits, which in turn lessened the logistical burden of maintaining and supplying different calibers throughout the fleet.
Despite all of the ships drawbacks and its unfortunate reputation, it remained the most powerful ship in service well into the end of the decade. By then, attitudes had shifted within naval circles towards building a better balanced fleet, capable of extending the range of the Lisenian navy further to sea.
