[5] After World War II, a larger number of veterans emerged, new posts were formed, and interest rose in creating an organization of national scope.

During the 1947 Convention of the Ukrainian Youth League of North America, several delegates met and expressed their desire to form such an association.

Major Michael Darmopray (Ukrainian transliteration: Darmohray, Дармограй) made the preparations for Post 1 to host a National Convention at the Penn Sheraton Hotel in Philadelphia, during Memorial Day Weekend of 1948 (May 29–31, 1948).

The authority of the Ukrainian American Veterans is vested in the National Executive Board (NEB), which meets quarterly or as needed, to conduct the business of the organization.

[10][11] Although individual Ladies Auxiliary units existed alongside UAV Posts prior to the 1948 Convention, a National organization did not materialize until March, 1974.

At the 27th UAV National Convention, in June 1974, at Jersey City, N.J., the Ladies Auxiliary was officially recognized as a part of the Ukrainian American Veterans organization.

A Constitution and By-Laws was adopted the following year, in June 1975, at the National Convention in Spring Valley, N.Y.[10][11] The Ukrainian American Veterans Ladies Auxiliary is an organization with dedicated, empowered women across the country, who are devoted to America's veterans, children and youth, with the notion of inspiring Auxiliary members' communities.

[13][14] At the National level, the UAV participated in a ceremony in Washington, D.C., on June 27, 1964, at the dedication of the Taras Shevchenko statue.

UAV National Commander Harry Polche was quoted during the ceremony: We stand here with pride and reverence, and we pause a moment to remember all the brave men who gave their lives for this country throughout its history.

They paid the supreme sacrifice for freedom, for human dignity, for everyone's hopes and dreams and rights, above all, for peace in the world.

The UAV Monument would be an ideal gathering place on St. Thomas Sunday and other holidays, to remember all Ukrainian American Veterans.

The by-laws of the fund changed several times over the years; the version adopted in 1992 is the one currently in use: The purpose of the National Welfare Fund is to provide assistance in the form of grants to veteran members, their families, or a Ukrainian American Veterans Post, as aid in times of distress; also to provide gifts or grants to the Ukrainian American men or women serving in the Armed Forces of the United States.

[22] This article provides grants to veterans who underwent major surgery, had a prolonged stay in the hospital, and were in dire need of funds.

To be eligible for a UAV scholarship, applicants must be descendants or related to a Ukrainian American Veteran and be a full-time matriculated college student in a degree program.

[25] In 1993, Robert Gulay of New Jersey Post 25 started the "Adopt a Hospital" project, with the assistance of NJ State Commander George A. Miziuk.

[26][27] In 1993, National Commander Roman Rakowsky wrote to President Bill Clinton, voicing his concern about the U.S. Veterans Administration distribution of duplicate medical journals to Russia, but not other former Soviet republics.

[28] From May 22 to June 1, 1995, the Armed Forces of the U.S. and Ukraine conducted joint peacekeeping exercises in the Lviv area, known as "Operation Peace Shield".

Since January 1995, Lt. Col. Yaro Oryshkevych M.D., D.C. Air National Guard, has been building a database of fluent Ukrainian speakers in both the active and reserve components of all branches of the service.

The Post sent hundreds of pounds of meat, rice and other provisions to the Mikhail Stenko in April and did the same for the Banner of October in August.

In 1978, New Jersey Governor Brendan Byrne signed Executive Order 65, which established the Ethnic Advisory Council in the state.

In 1994, Governor Christine Todd-Whitman appointed George A. Miziuk of N.J. Post 25 as a Ukrainian representative on the Ethnic Advisory Council.

[39] In addition to its formal activities, the UAV exists as a social group where members can share camaraderie with other American veterans of Ukrainian heritage.

Social activities, mainly organized at the Post level, can vary anywhere from barbecues, baseball games, and bingo, to banquets and ballroom dances.

In 1991, Ohio Post 24 and the Lviv-based Ukrainian Veterans of Afghanistan signed a “statement of understanding” to encourage a future relationship to exchange information.
