As monoplanes became popular, metal frames improved the strength, which eventually led to all-metal aircraft with metal covering all surfaces.

In the meantime, aircraft performance had improved tremendously ; compared to World War I versions, modern bombers could fly about twice as fast, at over twice the altitude, with much greater bomb loads.

Facing political concerns that the new fighters were not designed for the ground-attack role that had proven particularly useful in Iraq and Afghanistan, a plan to decommission the A-10 has been replaced with a plan to upgrade the existing aircraft with improved electronics, extending the service life of the planes until as late as 2028.

Later, the balance of power would shift periodically as each side obtained improved aircraft.

After American entry into the war late in 1941, the U. S. 8th Air Force began to develop a daylight bombing capacity using improved B-17 and B-24 four-engine aircraft.

A battery of wind tunnel tests followed, and although little else of the design was changed, including the wing profile ( NACA 0009 ), the performance of the aircraft was dramatically improved over straight-winged jets.

Britain took advantage of a lull in early 1942 to fly in 61 Supermarine Spitfires, which very much improved the defensive situation, although food, ammunition, and fuel were still critically short.

Angola-Portugal relations have significantly improved since the Angolan government abandoned communism and nominally embraced democracy in 1991, embracing a pro-U. S. and to a lesser degree pro-Europe foreign policy.

Another factor influencing the biotechnology sector's success is improved intellectual property rights legislation — and enforcement — worldwide, as well as strengthened demand for medical and pharmaceutical products to cope with an ageing, and ailing, U. S. population.

The U. S. Agency for International Development ( USAID ) mission is focused on improving access of underserved populations to quality health care and combating HIV / AIDS and tuberculosis ; promoting economic growth through policy reform, support for CAFTA-DR implementation, and technical assistance to small producers and tourism groups ; environmental protection and policy reform initiatives ; improved access to quality primary, public education and assistance to at-risk youth ; a model rural electrification program ; and improving participation in democratic processes, while strengthening the judiciary and combating corruption across all sectors.

Eisenhower's goal to create improved highways was influenced by difficulties encountered during his involvement in the U. S. Army's 1919 Transcontinental Motor Convoy.

Noticing the improved ability to move logistics throughout the country, he thought an Interstate Highway System in the U. S. would not only be beneficial for military operations, but provide a measure of continued economic growth.

However, conditions improved following a surge in U. S. troops in 2007-2008, and the war was declared formally over in December 2011, with the U. S. troops leaving the country.
